Description

Technical Field

[0001] This application relates to the field of semiconductor handling equipment technology, specifically to an OHT suspended lifting system and its roof mounting components. Background Technology

[0002] Overhead-Hoist Transportation (OHT) is a system for transporting materials in front-open unified pods (Foup). Due to its greater spatial flexibility, it is now widely used in automated material handling systems. For example, wafer transfer between semiconductor foundries (Fabs, wafer fabrications) is generally accomplished using OHT vehicles (also known as overhead transport vehicles) to connect various processes.

[0003] To meet the demands of integrated circuits, semiconductor manufacturers typically prioritize increasing production capacity and yield rates. To achieve these capacity targets, semiconductor wafer foundries commonly employ Out-of-Temperature (OHT) carts to automate the transfer of wafers between various devices. However, the widespread use of OHT carts in factories has brought about several challenges: how to quickly get the OHT carts onto tracks for operation, and how to maintain and service them.

[0004] Therefore, the common practice is to use an automated OHT lifting system (OHT Lifter) to solve the problem of quickly moving the OHT cart up and down the track, as well as to meet the needs of rapid deployment, subsequent maintenance, and upkeep of the OHT.

[0005] However, most current OHT lifting systems are based on lifting frames to lift and lower the OHT. Lifting frames have a large footprint and therefore require a lot of space in the workshop. Meanwhile, OHT lifters themselves are used relatively infrequently. As a result, the space wasted in the already very compact semiconductor workshop is very obvious. This further squeezes the space required for supporting facilities related to capacity improvement (such as the space required for storage and handling equipment), which is very detrimental to increasing the capacity of semiconductor manufacturing plants.

[0006] Although some efforts have been made to use suspended lifting systems to address the issue of space occupation in the workshop, the limited installation space between the overhead track (OHT running track) and the ceiling (roof) means that the suspended lifting system has not been able to effectively solve the space occupation problem. This results in poor flexibility in the deployment of the suspended lifting system in the workshop and prevents it from playing its due role in improving workshop productivity. Summary of the Invention

This not only facilitates flexible deployment of the OHT suspended lifting system within the workshop but also ensures high stability and reliability. Furthermore, when the suspended lifting system is not in use, its small overall footprint means that it does not occupy excessive workshop space or affect the normal operation of the OHT on the track.

[0049] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0050] The following specific examples illustrate the implementation of this application.

[0052] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not necessarily drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0053] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0054] Currently, a preliminary solution has been developed to use crossbeams to secure the suspended lifting system, thereby meeting the needs of OHT (Outdoor Lift) for access to the track, maintenance, and upkeep. While the crossbeam installation method provides good fixation for the suspended lifting system, the crossbeams require considerable installation space, and the suspended lifting system itself also occupies a certain amount of overhead space. Therefore, a significant amount of space needs to be reserved above the overhead track for the deployment of the lifting system.

[0055] In view of this, the inventors, through in-depth research and improvement exploration of aerial tracks, OHT suspended lifting systems, etc., discovered that:

[0056] On the one hand, in actual production workshops, overhead tracks are usually installed close to the ceiling, so the space between the overhead track and the ceiling is relatively limited, which makes it difficult to flexibly deploy the suspended lifting system in these narrow spaces for factory application deployment.

[0057] Secondly, in actual production workshops, the levelness of the ceiling structure itself may not meet the requirements of the lifting system, or due to production turnover needs, the height of the overhead track from the ceiling may vary. In particular, the actual deployed track usually cannot be guaranteed to be completely level. Therefore, it is also inconvenient to deploy a suspended lifting system in these limited spaces with varying heights.

[0058] Based on this, the embodiments of this specification propose a ceiling mounting component for an OHT suspended lifting system, which can make full use of the space between the overhead track and the ceiling to deploy the OHT suspended lifting system, while minimizing the space occupied by the OHT suspended lifting system, thereby facilitating the deployment of the OHT suspended lifting system in the overhead space of the workshop.

[0059] like Figure 1 As shown, an OHT suspended lifting system lifting assembly 2 (e.g., a belt assembly) is installed on the ceiling mounting assembly 1. The lower part of the lifting assembly 2 is connected to the lifting platform assembly 3. The lifting assembly 2 controls the lifting and lowering of the lifting platform assembly 3, facilitating a high-precision and stable docking of the lifting platform assembly 3 with the docking track 4. Specifically, the lifting assembly 2 controls the lifting platform assembly 3 to rise to a certain position for suspension from the ceiling or as shown in the diagram. Figure 1 The docking rail 4 shown is suspended below the ceiling mounting component 1; or the lifting component 2 controls the lifting platform component 3 to descend to a certain position, allowing ground personnel to perform a certain operation on it, or the lifting platform component 3 is docked with the docking rail 4 on the ground equipment.

[0060] Optionally, in some embodiments, the overhead electrical cabinet 5 is positioned on one side of the ceiling-mounted assembly 1 to further utilize the suspended space, while the ground control cabinet 6 is placed on the ground for convenient operation and control. Electrical connections are not part of the improvements intended by this invention and will not be elaborated upon here; however, they can be implemented with reference to prior art.

[0061] One end of the docking rail 4, suspended below the ceiling mounting assembly 1, is connected to the working rail of the OHT trolley (not shown in the figure), while the other end is an open docking end for docking with the lifting platform assembly 3. The aforementioned working rail refers to the rail (i.e., the overhead rail) suspended on the ceiling along which the OHT trolley travels when performing transport tasks.

[0062] When an OHT trolley needs to be lifted and pushed into its working track, the OHT trolley is mounted on the lifting platform assembly 3. After the lifting platform assembly 3 aligns with the docking rail 4 suspended below the ceiling mounting assembly 1, the OHT trolley on the lifting platform assembly 3 can move into the working track via the docking rail 4. Alternatively, when an OHT trolley requires maintenance, after the lifting platform assembly 3 aligns with the docking rail 4 suspended below the ceiling mounting assembly 1, the OHT trolley can enter through the docking rail and be mounted on the lifting platform assembly 3.

[0063] like Figures 2 to 3The ceiling mounting assembly may include: a frame body 101, an adjustable panel 102, and an adjustment mechanism 103. The frame body 101 is constructed from multiple suspension beams (e.g., four beams) connected by corner brackets 1012 to form an integral frame structure. This frame structure is fixed to the bottom of the ceiling (also known as the ceiling panel) via fasteners 1011. The adjustable panel 102 is made of a single, rigid panel, facilitating vertical adjustment via the adjustment mechanism.

[0064] The central part of the frame body 101 is an open space that can be used to accommodate or install other components as needed, or to allow other components to extend into the space.

[0065] The adjustment mechanism 103 includes a support plate 1031, an adjusting screw 1032, and a support block 1033. The support block 1033 is fixedly connected to the adjusting plate 102, and the support plate 1031 is fixedly connected to the frame body 101. The adjusting screw 1032 connects the support block 1033 and the support plate 1031. Furthermore, the adjusting plate 102 is positioned facing the ceiling. When the adjusting screw 1032 is adjusted, the adjusting plate 102 can be adjusted vertically, thereby providing a level overall installation plane for the OHT suspended lifting system.

[0066] Optionally, the support block 1033 and the adjusting plate 102 can be integrally formed and fixed together, or they can be configured as two components, the support block 1033 and the adjusting plate 102, which are fixed together by fasteners such as bolts.

[0067] Additionally, a support plate 1031 is installed below the suspension beam of the main frame 101 as a support. For example, the support plate 1031 is connected to the bottom of the suspension beam, serving as an integral support component to lift the large adjustment plate 102. Each adjustment mechanism 103 can use a screw to achieve a height adjustment structure, wherein the support plate is threadedly connected to the adjusting threaded rod (i.e., adjusting screw 1032), and the upper part of the adjusting screw 1032 is engaged in the slot of the support block 1033. When each adjusting screw 1032 is rotated, the up and down movement of different screws drives the corresponding positions of the large plate to move at the same / different heights, thereby realizing the height and / or horizontal adjustment of the large plate 102. This satisfies the requirements of an adjustable ceiling installation structure that can also compress the space above, making it easier to leave installation space for related mechanical structures, thus better connecting with the height of the existing track system in the factory workshop. The up and down adjustment through multiple adjusting screws 1032 supports and threads ensures both the strength of the support and the adjustability of the support plate.

[0068] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0069] This specification provides an embodiment of a ceiling mounting assembly for mounting an OHT suspended lifting system to a ceiling.

[0070] like Figures 2 to 10 As shown, the ceiling mounting assembly may include: a frame body 101, an adjustment plate 102, and several sets (e.g., 8 sets) of adjustment mechanisms 103.

[0071] In implementation, the main frame 101 includes multiple hanging beams that form an integral frame. Specifically, it can be an integral frame formed by connecting multiple hanging beams together through rigid corner brackets 1012. The main frame 101 can be installed and fixed to the bottom of the ceiling using fasteners 1011. It should be noted that the number, structure, and shape of the fasteners 1011 and corner brackets 1012 are not specifically limited.

[0072] In some embodiments, the fixed connection between the fixing member 1011 and the corner piece 1012 and the hanging beam can be a locking connection using a track locking member 1013. The hanging beam has a trapezoidal groove, into which the track locking member 1013 can be pre-embedded. This allows for quick adjustment of the positions of the fixing member 1011 and the corner piece 1012 on the hanging beam, locking the fixing member 1011, corner piece 1012, etc., onto the hanging beam. The locking structure can be found in [reference needed]. Figure 11 The schematic diagram shows the shape of the structure, which will not be elaborated upon further.

[0073] The adjusting plate 102, as a rigid integral plate, is set on the side of the frame body facing the ceiling, thus reserving more space below it for the installation of other mechanical structural components. Moreover, the adjusting plate can provide the lifting system with good structural characteristics such as flatness and levelness.

[0074] Each adjustment mechanism 103 includes a support plate 1031 and an adjustment screw 1032. The support plate 1031 is connected to the frame body 101, and the adjustment screw 1032 is connected to the adjustment plate 102. At this time, the adjustment screw 1032 can be used to support and adjust the adjustment plate 102 up and down, so that the level and height of the OHT suspended lifting system are installed on the lower surface of the adjustment plate 102 according to the preset requirements.

[0075] In some implementations, by setting up an interconnected structure between the support block, the adjusting screw, and the support plate, it is not only convenient to adjust and control the adjusting plate, but also to simplify the overall structure and facilitate installation.

[0076] refer to Figure 8 As shown, the upper side of the frame body 101 is connected to the ceiling, and the lower side of the frame body 101 faces the ground. Figure 8The vertical direction of the view corresponds to the height direction in the Fab workshop (unless otherwise specified by the context, the height direction mentioned in this invention refers to the height direction in the Fab workshop or a direction parallel to the height direction in the Fab workshop). The frame body 101 has a certain height H0 along the height direction, and the support plates 1031 in each adjustment mechanism 103 are fixed to the lower part of the frame body 101. Optionally, the top surface of the support plate 1031 can be set to be flush with or nearly flush with the bottom surface of the frame body 101. In this way, the frame body 101 and each support plate 1031 form an open receiving space, wherein the frame body 101 surrounds the perimeter of the receiving space, and the support plates 1031 surround the bottom of the receiving space near the edge.

[0077] Although the aforementioned accommodating space is an open space, according to the purpose of this embodiment, the distance along the height direction between the top surface of the support plate 1031 and the top surface of the frame body 101 can be defined as the first height H1 of the accommodating space. Thus, referring to... Figure 8 The lower end of the adjusting screw 1032 in each adjusting mechanism 103 is connected to the support plate 1031. The adjusting plate 102 is disposed in the aforementioned accommodating space, and the upper end of the adjusting screw 1032 in each adjusting mechanism 103 is connected to the adjusting plate 102. Thus, each adjusting screw 1032 supports the adjusting plate 102 above the support plate 1031. Therefore, each adjusting screw 1032 is configured such that when the adjusting screw 1032 is driven to rotate about its central axis in the height direction, it can control and drive the adjusting plate 102 to move at least in the height direction. The number of adjusting mechanisms 103 is greater than one.

[0078] Therefore, depending on the situation, roughly:

[0079] When only one or a portion of the adjusting screw 1032 of the adjusting mechanism 103 is rotated, the part of the adjusting plate 102 corresponding to the adjusting screw 1032 rises or falls, and the posture (i.e., levelness) of the adjusting plate 102 is changed.

[0080] Rotate all the adjusting screws 1032 of the adjusting mechanism 103, and the lifting height of the parts of the adjusting plate 102 corresponding to each adjusting screw 1032 is the same. At this time, the position of the adjusting plate 102 in the height direction is changed.

[0081] Alternatively, a combination of the above two situations can be used, rotating all the adjusting screws 1032 of the adjusting mechanism 103, but the lifting height of the parts of the adjusting plate 102 corresponding to at least some of the adjusting screws 1032 and the other part of the adjusting screws 1032 is different. In this case, the posture (i.e., levelness) and position in the height direction of the adjusting plate 102 are changed.

[0082] Obviously, regardless of which of the above adjustment situations applies, when the position or posture of the adjustment plate 102 is changed by rotating the adjustment screw 1032, it can be characterized by at least "a certain degree of change in the position of at least some areas on the adjustment plate 102 in the height direction".

[0083] For example, in one embodiment, the left and right sides of the adjusting plate 102 are each connected to the aforementioned adjusting screw 1032. If only the left adjusting screw 1032 is rotated, the left side of the adjusting plate 102 will rise or fall by a height ΔH1, while the right edge of the adjusting plate 102 remains unchanged. The overall tilt of the adjusting plate 102 changes. It can be seen that, theoretically, the rising or falling height is different from the left side to the right side of the adjusting plate 102. The rising or falling height ΔH1 is the largest at the left edge, and the rising or falling height gradually decreases towards the right side. Therefore, the overall rising or falling range of the adjusting plate 102 can be defined as 0 to ΔH1.

[0084] Of course, in other embodiments, the adjusting plate 102 may not be limited to connecting the adjusting screw 1032 on the left and right sides. The adjusting screw 1032 may also be selectively connected at the diagonal, front, and rear positions of the adjusting plate 102. Therefore, the overall lifting and lowering of the adjusting plate 102 is not limited to one dimension, but may also be two dimensions. However, it is obvious that there is a maximum amplitude ΔHmax among the amplitudes at various parts of the adjusting plate 102.

[0085] In some embodiments, the range ΔHmax of the adjustment of the large panel 102 and the first height H1 of the aforementioned accommodating space satisfy: ΔHmax ≤ H1. Thus, the relative positional arrangement between the large panel 102 and the frame body 101 in the height direction, as well as the connection and installation of the adjustment mechanism 103 between the large panel 102 and the frame body 101, have the advantages of being structurally compact and having high space utilization.

[0086] Obviously, in some embodiments, the layout of the support plate 1031 and the frame body 101 is not limited to: the top surface of the support plate 1031 may be set to be flush with or nearly flush with the bottom surface of the frame body 101. The layout of the support plate 1031 and the frame body 101 can also be modified such that: the bottom surface of the support plate 1031 is set to be flush with or nearly flush with the bottom surface of the frame body 101, or modified to other relative positional relationships, such as the support plate 1031 being fixed to the lower middle or middle part of the frame body 101, etc. In this way, the above-mentioned accommodating space can also be formed around the frame body 101 and each support plate 1031.

[0087] In some embodiments, the frame body 101 and each support plate 1031 surround and form the aforementioned receiving space, which also makes the construction process of installing the ceiling mounting components onto the ceiling more convenient and safer.

[0088] On the one hand, when the frame body 101 is connected to the bottom of the ceiling, the support plate 1031 blocks the bottom edge of the accommodating space. At this time, it is easier to place the adjustment plate 102 above the support plate 1031. With the support plate 1031 firmly connected to the frame body 101, the support plate 1031 or the adjustment screw 1032 on the support plate 1031 can block the adjustment plate 102 from falling off and causing safety hazards. At the same time, it also facilitates the subsequent operation of the installers.

[0089] On the other hand, multiple adjustment mechanisms 103 are provided around the accommodating space, so that even if, for example, one of the adjustment mechanisms 103 fails, the support plate 1031 can block it from falling under the adjustment plate 102, thus preventing more serious failures / abnormalities from occurring.

[0090] like Figures 4 to 10 The support block 1033 has an opening, and one end of the adjusting screw 1032 has a stepped groove (similar to a head structure with protrusions at the top and bottom and a recess in the middle, like a screw head). When the stepped groove of the adjusting screw 1032 is engaged in the opening of the support block 1033, the adjusting screw 1032 will be engaged with the support block 1033 through the stepped groove under the adjustment of the threaded connection between the adjusting screw 1032 and the support plate 1031.

[0091] In some embodiments, a mating part is also provided between the support block and the adjusting plate, so that the mating part not only facilitates the mating connection, but also facilitates the fastening connection between the support block and the adjusting plate.

[0092] like Figures 4 to 10 As shown, the edge of the support block 1033 is provided with a first protrusion-shaped part (e.g., Figure 9 In the illustration, the edge of the support block 1033 is the first step, and the middle of the support block 1033 is the second step. Similarly, a first groove-shaped part is provided in the adjusting plate 102 (e.g., Figure 9 In the illustration, the portion of the adjusting plate 102 slightly farther from the edge is designated as the first recess, and the portion closer to the edge is designated as the second recess. Therefore, the first recessed portion engages with the first protruding portion to tighten the screws (e.g., Figure 9 (The screw is shown as protruding slightly from the adjusting plate 102 near the adjusting screw 1032.) The support block 1033 and the adjusting plate 102 are fixedly connected by the mating part, which also makes it very convenient for positioning and alignment during installation.

[0093] refer to Figure 9 As shown, in some embodiments, the support plate 1031 is provided with a threaded hole, and the lower part of the adjusting screw 1032 is screwed into the threaded hole, thereby connecting the adjusting screw 1032 and the support plate 1031 through a threaded engagement. When the adjusting screw 1032 is rotated, the adjusting screw 1032 can move up and down relative to the support plate 1031. The upper part of the adjusting screw 1032 is provided with a first annular boss and a rotating engagement part from bottom to top. Optionally, the upper part of the adjusting screw 1032 is provided with a first annular boss, a rotating engagement part, and a second annular boss part from bottom to top. The support block 1033 is sleeved on the outside of the rotating engagement part on the adjusting screw 1032.

[0094] On the adjusting screw 1032, the outer diameter of the first annular boss is larger than the outer diameter of the rotating mating part, thus forming a step at the junction of the first annular boss and the rotating mating part. The upper end face of the first annular boss abuts against the lower side of the support block 1033, thereby supporting the adjusting plate 102.

[0095] Optionally, when the second annular boss portion is provided, the outer diameter of the second annular boss is larger than the outer diameter of the rotary mating portion, thereby forming another step at the junction of the second annular boss and the rotary mating portion. The lower end face of the second annular boss can block the upper side of the support block 1033 to improve stability.

[0096] Optionally, an opening is provided at the edge of the support block 1033, and the rotating mating part of the adjusting screw 1032 can be easily inserted into the opening from the side to complete the mating installation. It is easy to understand that, not limited to the opening connection method in the foregoing embodiments, the second annular boss can be integral with the adjusting screw 1032; it can also be modified to a hole connection method, where the second annular boss can be an independent component and then constructed by riveting, welding, or a method such as connecting nuts.

[0097] In this invention, the first and second annular bosses, wherein the shape of "annular" is not limited to a standard circle, but can be an ellipse or a deformed protruding structure, refers to one or more structures that are continuously or intermittently arranged around the outer wall of the adjusting screw 1032 in the circumferential direction and protrude outward in the radial direction, which can form a step and play a supporting / limiting role.

[0098] The upper part of the adjusting screw 1032 is rotatably engaged with the support block 1033, and the lower part of the adjusting screw 1032 is rotatably and vertically engaged with the support plate 1031. Therefore, in the circumferential direction, when the adjusting screw 1032 is rotated, the support block 1033 does not rotate. While the adjusting screw 1032 moves up and down, the support block 1033 moves up and down along with the adjusting plate 102.

[0099] In some embodiments, the above embodiments can be modified such that the upper part of the adjusting screw 1032 is configured with a rotatable and liftable threaded engagement with the support block 1033, and the lower part of the adjusting screw 1032 is configured with a rotatable engagement with the support plate 1031. The support block 1033 has a threaded hole, into which the adjusting screw 1032 is screwed. The lower part of the adjusting screw 1032 has a rotating engagement portion, and the support plate 1031 has an opening or hole that fits onto the outside of the rotating engagement portion. Thus, when the adjusting screw 1032 is rotated, the threaded engagement between the support block 1033 and the adjusting screw 1032 also drives the support block 1033 to move up and down, along with the adjusting plate 102.

[0100] In some implementations, the support plate is fastened to the lifting beam by using a locking structure, which not only simplifies the installation process but also makes the fixed connection more reliable after locking.

[0101] like Figure 2 , Figures 4 to 10 As shown, the support plate is provided with multiple track connecting blocks 10311, which are embedded in the grooves in the hanging beam. After being embedded in the grooves, the support plate 1031 and the frame body 101 can be quickly locked together by adjustment.

[0102] In some embodiments, some support plates can be set at the corners of the frame body 101. For example, support plates 1031 are respectively set at the four corners of the frame body 101, so that the support plates 1031 can provide good support for the frame body 101, so that the frame body 101 can still provide good rigidity even in a small volume.

[0103] In some implementations, since the space below the adjustment plate 102 can be accommodated, relevant components of the OHT suspended lifting system can be installed using some structural components.

[0104] like Figure 2 The ceiling mounting assembly also includes several first hoisting assemblies 104. One end of each first hoisting assembly 104 is fixedly connected to the lower surface of the adjusting plate 102, and the other end of each first hoisting assembly is used to connect with the OHT suspended lifting system. The height of each first hoisting assembly is not less than the height of the wireless power source of the OHT suspended lifting system.

[0105] In some examples, the first lifting assembly 104 may be a pin alignment and self-locking device, for example, when the aforementioned Figure 1 When the illustrated lifting platform assembly rises to the preset height, it is aligned using the four corner pins and then locked in place. (Reference) Figure 13 and Figure 14 As shown, the pin 301 of the lifting platform component 3 is connected to the first hoisting component 104, and the height of the first hoisting component 104 is not less than the height of the wireless power supply 302. Thus, the connection between the first hoisting component 104 and the lifting platform component 3 can not only achieve alignment and locking, but also provide corresponding installation space for the wireless power supply 302. This is beneficial for deploying and applying the wireless power supply 302 in the OHT suspended lifting system, further saving the space occupied by the OHT suspended lifting system and facilitating the flexible deployment and application of the OHT suspended lifting system in factory workshops.

[0106] like Figure 2 The ceiling mounting assembly also includes several belt sensors 107, such as a first belt sensor 1071 and a second belt sensor 1072. These belt sensors are located on the lower surface of the adjustment plate 102, so that the relative height position of the lifting platform assembly 3 connected to the belt below in the OHT suspended lifting system can be obtained through the detection results of these belt sensors.

[0107] For example, the first belt sensor 1071 and the second belt sensor 1072 constitute a through-beam detection device, which can roughly detect and judge whether the thickness of the belt wound on the winding drum of the flexible belt in the lifting assembly 2 is adequate. For example, during the ascent, the flexible belt is gradually wound onto the winding drum, at which time the winding drum with the synchronous belt becomes thicker and its outer diameter gradually increases. The positions of the first belt sensor 1071 and the second belt sensor 1072 are configured such that when the lifting platform rises to a preset height, the belt is wound up, and the thickness of the belt roll becomes so thick that it blocks the space between the first belt sensor 1071 and the second belt sensor 1072. At this time, the two sensors are triggered to output detection results. It is easy to understand that when the lifting platform descends or the height does not reach the aforementioned preset height, there is no obstruction between the first belt sensor 1071 and the second belt sensor 1072, and therefore no detection result is output.

[0108] In practice, the belt sensor can be fixedly connected to the adjusting plate 102 through an L-shaped structural component, and the L-shaped structural component (such as the first belt sensor 1071) can also be a structural component with reinforcing ribs to improve the rigidity of the component structure.

[0109] like Figure 2 The ceiling mounting assembly also includes several second hoisting assemblies 108, wherein the second hoisting assemblies 108 are fixedly connected to the lifting beam of the frame body 101. In this case, the second hoisting assemblies 108 can be used to suspend the electrical control box of the OHT suspended lifting system (see the aforementioned...). Figure 1 (Illustrated electrical control box).

[0110] In some implementations, considering that the lifting platform can wirelessly draw power from the electrical control box, a fixed bracket can be installed below the adjusting plate to support the wireless power-drawing structure in the space below the adjusting plate.

[0111] like Figure 2 and Figure 12 This diagram illustrates that after suspending the electrical control box using the second hoisting assembly, the cable of the electrical control box can be led out to the space below the adjusting plate 102 to achieve a wireless power supply solution. Specifically, the ceiling mounting assembly also includes a wireless power supply assembly 106, which is fixed and supported by several fixed brackets 1062. The fixed brackets 1062 are located on the lower surface of the adjusting plate 102 and support the cable 1061 that provides wireless power to the electrical control box, thereby facilitating the wireless power supply device (not shown in the figure) in the OHT suspended lifting system to wirelessly draw power from the cable 1061.

[0112] In some implementations, by setting relevant detection components in the space below the adjustment plate, the relevant operations (such as lifting) of the OHT suspended lifting system can be detected and controlled in real time.

[0113] like Figure 2 , Figures 15 to 16 The canopy mounting assembly also includes several detection components 109, which are disposed in the space below the adjusting plate 102 and are used to detect the OHT suspended lifting system. Specifically, two sets of detection components 109 are arranged facing the lifting platform of the OHT suspended lifting system.

[0114] Preferably, the detection component 109 may include a first detection end 1091 and a second detection end 1092, wherein the first detection end 1091 is installed on the lower surface of the adjustment plate 102, and the second detection end 1092 is installed on the lifting platform 3 of the OHT suspended lifting system so as to follow the lifting platform up or down, thereby completing the detection of the main lifting position through the cooperation between the first detection end and the second detection end.

[0115] In one example, such as Figures 15 to 17The first detection end 1091 of the detection assembly 109 employs three detectors (namely, the first detector 10911, the second detector 10912, and the third detector 10913), which are mounted on the lower surface of the adjustment plate 102. The second detection end 1092 of the detection assembly 109 uses baffles at different positions to cooperate with photoelectric detectors for detection, such as the first baffle and the second baffle. These baffles are mounted on the lifting platform of the OHT suspended lifting system. Therefore, photoelectric detectors are preferred, so that the baffles and photoelectric detectors cooperate to complete the detection.

[0116] Preferably, such as Figure 16 As shown, the same baffle structure 10921 can be used. By setting different height positions of the baffle structure 10921, the functions of the first baffle and the second baffle can be realized respectively, further reducing the space occupation. The mounting base 10922 is used for connection with the lifting platform 3 (reference). Figures 13 to 14 (Illustration)

[0117] In one example, the detector and the baffle can be used to detect the results and achieve related operations, such as wireless power supply.

[0118] For example, when the lifting platform of the OHT suspended lifting system rises towards the ceiling, the first baffle first cooperates with the first detector 10911 to detect that the lifting platform is about to approach the ceiling, thus preparing for wireless power supply. If the lifting platform continues to rise, the first baffle cooperates with the second detector 10912 to detect that the lifting platform has entered the range where wireless power can be supplied, thus enabling wireless power supply operation. If the lifting platform continues to rise, the second baffle cooperates with the third detector 10913 to detect that the lifting platform has reached the limit state, thus stopping the rise and providing continuous power supply for wireless power supply, achieving stable and reliable wireless power supply.

[0119] For example, when the lifting platform descends from the ceiling, the corresponding operation (such as disconnecting the wireless power supply) can also be completed through the cooperation between the detector and the baffle, which will not be explained further.

[0120] In some implementations, good electromagnetic shielding can be achieved by utilizing the space under the adjustable plate, reducing electromagnetic interference that may be caused by the wireless power supply cable, which helps to improve reliability.

[0121] like Figure 2The ceiling mounting assembly also includes a cable shielding duct 105, which can be specifically laid out according to the space constraints below the adjustment plate 102, and is set on the lower surface of the adjustment plate 102 by several support members 1051. The cable shielding duct 105 can be a duct capable of shielding electromagnetic signals, thereby enabling quantified shielding of electromagnetic signals emitted by the cable 1061 between the electrical control box and the wireless power source.

[0122] In some embodiments, the frame body 101 in the foregoing embodiments may be an integral frame consisting of four hanging beams. In this case, the number of adjustment mechanisms 103 is set to eight, with four sets of adjustment mechanisms 103 located at the corners of the frame body 101 and four sets of adjustment mechanisms 103 located in the middle of the corresponding hanging beams. This not only provides good support for the frame body 101, but also provides good support for the adjustment plate 102.

[0123] Based on the same inventive concept, this application also provides an OHT suspended lifting system. (Refer to the foregoing) Figure 1 As illustrated, the OHT suspended lifting system is fixedly installed under the ceiling using any of the ceiling mounting components described in this specification. This not only makes full use of the space between the track and the ceiling, but also facilitates the flexible deployment and application of the OHT suspended lifting system in the workshop.

In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
