Description

OHT suspension type lifting system and ceiling installation assembly thereof

Technical Field

The application relates to the technical field of semiconductor handling equipment, in particular to an OHT suspension type lifting system and a ceiling installation assembly thereof.

Background

An Overhead-host-transfer (OHT) system is a system for handling wafer cassette materials (Foup: front Open Unified Pod) and is widely used in automated material handling systems, such as wafer Fab (Fab) for transferring wafers between various processes, because of its greater spatial freedom.

To meet the demands of integrated circuits, semiconductor manufacturing enterprises generally aim to improve productivity and yield. In order to achieve the throughput goal, OHT carts are currently commonly used in semiconductor foundry to enable automated handling of wafers for transfer between devices through the OHT carts. However, after the OHT vehicles are used in large quantities in factories, there are following problems: how to quickly let the OHT trolley enter the track for running, how to perform maintenance, service, etc. on the OHT.

For this reason, it is common practice to use an automated OHT lift system (OHT Lifter) to solve the problem of rapid up-down track of the OHT trolley, and to meet the requirements of rapid deployment, post maintenance, and maintenance of the OHT.

However, most of the OHT lifting systems (OHT Lifter) at present are based on the scheme of lifting the OHT by using a lifting frame, the lifting frame occupies a large area, and therefore, more space is necessarily required to occupy a workshop, and the OHT Lifter itself is relatively low in use frequency, so that the space waste of the semiconductor workshop which is very compact originally is very obvious, the space waste of the related supporting space (such as the space required by a storage warehouse and the space required by a carrying device) for capacity lifting is further occupied, and the capacity lifting of a semiconductor manufacturing factory is very unfavorable.

Although suspension-type lifting systems have been primarily used to solve the problem of occupation of the shop space as much as possible, they are limited by the narrow installation space of the overhead track (i.e., OHT track) from the ceiling (i.e., roof), and the suspension-type lifting systems still cannot effectively solve the problem of occupation of the space, resulting in poor flexibility of the suspension-type lifting systems in the deployment of the shop, and cannot exert the due effect that the OHT lifting systems can contribute to the capacity lifting of the shop.

In addition, in the following description, specific details are provided in order to provide a thorough understanding of the examples. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details.

Currently, there are preliminary proposals for securing suspended lifting systems with beams to meet the needs of OHT access to the track, maintenance, servicing, etc. By adopting the mounting mode of the cross beam, although the hanging type lifting system can be well fixed, the cross beam needs more mounting space, and the hanging type lifting system also needs to occupy a certain space in the air, so that a great amount of space is reserved above the air track to deploy the lifting system.

In view of this, the inventors have conducted intensive studies and improved searches on an air track, an OHT suspended hoisting system, and the like, and found that:

On the one hand, in actual production plants, the overhead rails are usually installed close to the ceilings, so that the space between the overhead rails and the ceilings is limited, and the suspended lifting system cannot flexibly deploy factory application in these narrow spaces;

in the actual production workshop, the levelness of the ceiling (ceiling) structure cannot necessarily meet the requirement of a lifting system, or the height of the overhead track from the ceiling is different due to production turnover requirements, and particularly, the actual deployment track cannot generally ensure a completely horizontal state, so that the suspended lifting system is inconvenient to deploy in limited spaces with different heights.

Based on this, the embodiment of the specification provides a ceiling installation component of an OHT suspended lifting system, which not only can fully utilize the space between an overhead track and a ceiling to deploy the OHT suspended lifting system, but also can reduce the occupation of the OHT suspended lifting system to the space as much as possible, thereby facilitating the overhead deployment of the OHT suspended lifting system in a workshop.

As shown in fig. 1, an OHT suspended lifting system lifting and lifting assembly 2 (e.g., a belt assembly) is mounted on a ceiling mounting assembly 1, the lower part of the lifting and lifting assembly 2 is connected with a lifting platform assembly 3, and the lifting and lifting assembly 2 controls the lifting and lifting of the lifting platform assembly 3, so that the lifting platform assembly 3 and a docking track 4 can be conveniently and stably docked with high precision. Wherein the lifting and lifting assembly 2 controls the lifting and lifting platform assembly 3 to be lifted to a certain position so as to be convenient to be hung on a ceiling or to be hung below the ceiling mounting assembly 1 as shown in fig. 1 for docking with the docking rail 4; or the lifting and lowering assembly 2 controls the lifting and lowering platform assembly 3 to a position that allows a person on the ground to do something to it or the lifting and lowering platform assembly 3 interfaces with the docking track 4 on the equipment on the ground.

Optionally, in some embodiments, the aerial regulator cubicle 5 is disposed at one side of the ceiling mounting assembly 1 to further make full use of the suspended space, and the ground control cubicle 6 is placed on the ground, so as to facilitate personnel operation control. The electrical connection is not part of the intended improvement of the present invention, and is not described herein and may be implemented with reference to known technologies.

One end of the docking rail 4 suspended below the ceiling mount assembly 1 is connected to a working rail (not shown) of the OHT car, and the other end is a docking end that is open and is used for docking with the elevating platform assembly 3. The working track refers to a track (i.e., an overhead track) along which an OHT vehicle suspended from a ceiling travels when performing a transport task.

When an OHT vehicle needs to be lifted and pushed into the working track of the OHT vehicle, the OHT vehicle is carried on the lift platform assembly 3, and after the lift platform assembly 3 is docked with the docking track 4 suspended below the ceiling mounting assembly 1, the OHT vehicle on the lift platform assembly 3 can be driven into the working track through the docking track 4. Alternatively, when an OHT vehicle needs maintenance, after the lift platform assembly 3 completes docking with the docking rail 4 suspended below the ceiling mounting assembly 1, the OHT vehicle may enter through the docking rail and be carried on the lift platform assembly 3.

As illustrated in fig. 2-3, the ceiling mounting assembly may include: a frame body 101, an adjustment large plate 102, and an adjustment mechanism 103. Wherein, the frame main body 101 adopts a plurality of hanging beams (such as four beams) to form an integral frame structure through angle pieces 1012, and the frame structure is fixed under a ceiling (also called a ceiling) through fixing pieces 1011; the adjusting large plate 102 is made of a monolithic plate (such as a monolithic plate with good rigidity), and is convenient to adjust up and down through an adjusting mechanism.

The middle of the frame body 101 is an open space that can be used to accommodate or mount other components as needed or to allow other components to extend into the space.

The adjusting mechanism 103 includes a support plate 1031, an adjusting screw 1032, and a support block 1033, the support block 1033 is fixedly connected with the adjusting large plate 102, the support plate 1031 is fixedly connected with the frame body 101, and the adjusting screw 1032 is coupled between the support block 1033 and the support plate 1031. In addition, the adjusting large plate 102 is disposed toward the ceiling side, and when the adjusting screw 1032 adjusts, the adjusting large plate 102 can be adjusted up and down, thereby providing an integral installation plane with good levelness for the OHT suspension-type lifting system through the adjusting large plate 102.

Alternatively, the supporting block 1033 and the adjusting large plate 102 may be integrally formed and fixed together, or may be formed by two parts of an assembly of the supporting block 1033 and the adjusting large plate 102, and fixed together by fastening means such as bolts.

In addition, a supporting plate 1031 is installed as a support at a position below the hanging beam of the frame body 101, for example, the supporting plate 1031 is connected to the bottom of the hanging beam, and as an integral support, the adjusting large plate 102 is jacked up; each adjustment mechanism 103 may be implemented as a height adjustment mechanism using a screw, wherein the support plate is screwed with an adjusted threaded rod (i.e., adjustment screw 1032), and the top of the adjustment screw 1032 is snapped into a snap-in groove of the support block 1033. When each adjusting screw 1032 is rotated, the up-and-down lifting of different screws drives the lifting movement of the same/different heights at each corresponding position of the large plate, thereby realizing the height and/or horizontal adjustment of the large plate 102, meeting the ceiling installation structure which is adjustable and can compress the upper space, being convenient for leaving installation space for related mechanical structures, and better docking the height of the existing track system in a factory workshop; the support and threads of the adjusting screw 1032 at a plurality of positions are adjusted up and down, so that the strength of the support is ensured, and the adjustability of the support plate is also ensured.

The following describes the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Embodiments of the present disclosure provide a ceiling mount assembly for mounting an OHT overhead hoist system to a ceiling.

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

In practice, the frame body 101 includes a plurality of hanging beams, and the plurality of hanging beams enclose a monolithic frame, specifically, may be a monolithic frame formed by interconnecting a plurality of hanging beams through corner pieces 1012 with good rigidity. The frame body 101 can be attached and fixed to the underside of the ceiling by fixing members 1011. The number, the structural shape, and the like of the fixing members 1011 and the corner members 1012 are not particularly limited.

In addition, in some embodiments, the fixed connection between the fixing member 1011 and the corner member 1012 and the hanging beam may be a locking type fixed connection using the track locking member 1013, wherein the hanging beam is provided with a trapezoidal-like chute, so that the track locking member 1013 may be pre-inserted into the chute, thereby enabling quick adjustment of the position according to the fixing position of the fixing member 1011 and the corner member 1012 on the hanging beam, and locking the fixing member 1011, the corner member 1012, etc. on the hanging beam, and the locking structure may be referred to the schematic structural shape of fig. 11, and is not unfolded later.

The adjusting large plate 102 is used as an integral plate with good rigidity and is arranged on one side of the frame body facing the ceiling, so that more space is reserved below the frame body for installing other mechanical structural members, and good structural characteristics such as flatness, levelness and the like can be provided for the lifting system based on the adjusting large plate.

Each set of adjusting mechanism 103 comprises a supporting plate 1031 and an adjusting screw 1032, the supporting plate 1031 is connected with the frame body 101, the adjusting screw 1032 is connected with the adjusting large plate 102, at this time, the adjusting screw 1032 can be used for supporting and adjusting the adjusting large plate 102 up and down, so that the levelness, the height and the like of the OHT suspension type lifting system are mounted on the lower surface of the adjusting large plate 102 according to preset requirements.

In some embodiments, through setting up interconnect structure between supporting shoe, adjusting screw and the backup pad, not only can conveniently adjust control to adjusting the big board, simplify overall structure moreover, be favorable to the installation.

Referring to fig. 8, the upper side of the frame body 101 is connected to a ceiling, and the lower side of the frame body 101 faces the ground. The up-down direction of the view direction of fig. 8 corresponds to the height direction in the Fab-shop (unless otherwise specified in context with the context, the height directions mentioned in the present invention are all the height directions in the Fab-shop or the directions parallel to the height directions in the Fab-shop). The frame body 101 has a height H0 in the height direction, and the support plate 1031 of each adjustment mechanism 103 is fixed to the lower portion of the frame body 101. Alternatively, the top end surface of the support plate 1031 may be disposed flush or nearly flush with the bottom end surface of the frame body 101, such that the frame body 101 and each support plate 1031 enclose an open accommodation space, wherein the frame body 101 surrounds the accommodation space, and the support plate 1031 surrounds the bottom of the accommodation space at a position adjacent to the edge.

Although the accommodation space is a non-closed space, according to the purpose of the present embodiment, a distance in the height direction from the top end surface of the support plate 1031 to the top end surface of the frame body 101 may be defined as a first height H1 of the accommodation space. As such, referring to fig. 8, the lower end of the adjusting screw 1032 in each adjusting mechanism 103 is coupled to the support plate 1031, the adjusting large plate 102 is disposed in the aforementioned accommodation space, and the upper end of the adjusting screw 1032 in each adjusting mechanism 103 is coupled to the adjusting large plate 102, so that each adjusting screw 1032 supports the adjusting large plate 102 above the support plate 1031. Thus, each adjusting screw 1032 is configured to: when the adjusting screw 1032 is driven to rotate around its central axis in the height direction, the adjusting plate 102 is controlled and driven to move at least in the height direction, wherein the number of the adjusting mechanisms 103 is greater than 1.

Thus, there are, as the case may be:

when only one or a part of the adjusting screw 1032 of the adjusting mechanism 103 is rotated, the position of the adjusting large plate 102 corresponding to the adjusting screw 1032 is raised or lowered, and the posture (i.e., levelness) of the adjusting large plate 102 is changed;

the adjusting screws 1032 of all the adjusting mechanisms 103 are rotated, and the lifting heights of the positions of the adjusting large plates 102 corresponding to the adjusting screws 1032 are the same, and at this time, the positions of the adjusting large plates 102 in the height direction are changed;

Alternatively, in combination of the above two cases, the adjustment screws 1032 of all the adjustment mechanisms 103 are rotated, but at least a part of the adjustment screws 1032 and the other part of the adjustment screws 1032 are different in elevation height from each other at the position of the adjustment large plate 102, and at this time, the posture (i.e., levelness) and the position in the height direction of the adjustment large plate 102 are changed.

It is apparent that, in any of the above adjustment cases, when the adjustment screw 1032 is rotated to change the position or posture of the adjustment large plate 102, it can be characterized by at least "a certain amplitude of change in the position in the height direction of at least a partial region on the adjustment large plate 102".

For example, in one embodiment, the left and right sides of the adjusting plate 102 are respectively connected with the adjusting screws 1032, and if only the left adjusting screw 1032 is turned, the left portion of the adjusting plate 102 is lifted by a height Δh1, the right edge of the adjusting plate 102 is not moved, and the whole inclination of the adjusting plate 102 is changed, wherein, from the left side to the right side of the adjusting plate 102, the lifting heights of the left edge are theoretically different, the lifting height Δh1 of the left edge is the largest, and the lifting height gradually decreases toward the right area, so that the whole lifting amplitude of the adjusting plate 102 can be defined as 0 to Δh1.

Of course, in other embodiments, the adjusting large plate 102 may be coupled to the adjusting screw 1032 not only on the left side and the right side, but also on the diagonal, front side, rear side, etc. of the adjusting large plate 102, and thus, the overall lifting and lowering of the adjusting large plate 102 is not limited to one dimension, but may be two-dimensional, but it is apparent that there is a maximum amplitude Δhmax among the amplitudes at the respective portions of the adjusting large plate 102.

In some embodiments, the adjustment of the height Δhmax of the lifting of the large plate 102 and the first height H1 of the accommodating space satisfy: ΔHmax is less than or equal to H1. In this way, in the height direction, the relative position layout between the adjustment large plate 102 and the frame main body 101, and the coupling and mounting of the adjustment mechanism 103 between the adjustment large plate 102 and the frame main body 101 have advantages of compactness in structure and high space utilization.

Obviously, in some embodiments, the layout of the support plate 1031 and the frame body 101 is not limited to: the top end surface of the support plate 1031 may be disposed flush or nearly flush with the bottom end surface of the frame body 101. The layout of the support plate 1031 and the frame body 101 can also be modified as follows: the bottom end surface of the support plate 1031 is flush or nearly flush with the bottom end surface of the frame body 101, or is deformed into other relative positional relationship, for example, the support plate 1031 is fixed to the middle lower portion or middle portion of the frame body 101, so that the above-described accommodation space may be formed around between the frame body 101 and each support plate 1031.

In some embodiments, the frame body 101 and each support plate 1031 surround and form the accommodation space therebetween, and also facilitate and secure the construction process of mounting the ceiling mounting assembly to the ceiling.

On the one hand, when the frame body 101 is connected to the lower side of the ceiling, the supporting plate 1031 is blocked at the bottom edge of the receiving space, at this time, the adjusting large plate 102 can be more easily placed above the supporting plate 1031, and in the case of ensuring that the supporting plate 1031 is already firmly coupled to the frame body 101, the supporting plate 1031 or the adjusting screw 1032 on the supporting plate 1031 can be blocked below the adjusting large plate 102, the adjusting large plate 102 is not easily dropped to generate a safety hazard, and at the same time, the subsequent operation of the installer is also facilitated.

On the other hand, a plurality of adjustment mechanisms 103 are provided around the accommodation space, and even in the event of, for example, a failure of an individual adjustment mechanism 103, the support plate 1031 can be blocked below the adjustment large plate 102, avoiding a more serious failure/abnormality.

As illustrated in fig. 4 to 10, the supporting block 1033 is provided with an opening, and one end of the adjusting screw 1032 is provided with a stepped recess (such as a head structure like a screw head protruding up and down and recessed in the middle), so that when the stepped recess of the adjusting screw 1032 is caught in the opening of the supporting block 1033, the adjusting screw 1032 will clamp the supporting block 1033 through the stepped recess under the adjustment of the screw connection of the adjusting screw 1032 with the supporting plate 1031.

In some embodiments, the matching part is also arranged between the supporting block and the adjusting large plate, so that the matching part is convenient for matching connection, and fastening connection between the supporting block and the adjusting large plate is facilitated.

As shown in fig. 4 to 10, the edge of the supporting block 1033 is provided with a first boss-shaped portion (for example, in the illustration of fig. 9, the edge portion of the supporting block 1033 is a first step, and the middle portion of the supporting block 1033 is a second step), and similarly, a first groove-shaped portion is provided in the adjusting large plate 102 (for example, in the illustration of fig. 9, a portion of the adjusting large plate 102, which is slightly far from the edge, is provided with a first concave portion, and a portion of the adjusting large plate is provided with a second concave portion), so that the first groove-shaped portion cooperates with the first boss-shaped portion, and thus, a fastening screw (for example, in the illustration of fig. 9, a screw protruding slightly from the adjusting large plate 102 in the vicinity of the adjusting screw 1032) realizes a good fixed connection between the supporting block 1033 and the adjusting large plate 102 based on the cooperation portion, and the cooperation portion is also very convenient for positioning, alignment, etc. in the installation.

Referring to fig. 9, in some embodiments, a threaded hole is provided in the support plate 1031, and a lower portion of the adjustment screw 1032 is screwed into the threaded hole, so that the adjustment screw 1032 is coupled to the support plate 1031 by a threaded engagement, and the adjustment screw 1032 is movable up and down relative to the support plate 1031 when the adjustment screw 1032 is rotated. The upper part of the adjusting screw 1032 is provided with a first annular boss and a rotary matching part from bottom to top. Optionally, a first annular boss, a rotation matching portion, and a second annular boss portion are sequentially provided from bottom to top at an upper portion of the adjusting screw 1032. The supporting block 1033 is sleeved outside the rotating fitting portion on the adjusting screw 1032.

On the adjusting screw 1032, the outer diameter of the first annular boss is larger than the outer diameter of the rotation fitting portion, and a step is formed at the position where the first annular boss adjoins the rotation fitting portion, and the upper end face of the first annular boss abuts against the lower side of the supporting block 1033 to support the adjusting large plate 102.

Optionally, in the case of the second annular boss portion, the outer diameter of the second annular boss portion is larger than the outer diameter of the rotation fitting portion, and further another step is formed at the position where the second annular boss and the rotation fitting portion abut, and the lower end surface of the second annular boss may be blocked at the upper side of the supporting block 1033 to improve stability.

Optionally, an opening is provided at the edge of the support block 1033, into which the rotational mating portion of the adjustment screw 1032 can be easily inserted from the side to complete the mating installation. It is readily understood that the second annular boss may be integral with the adjusting screw 1032, not limited to the manner of opening coupling in the previous embodiments; the second annular boss may be formed as a separate component by riveting, welding, or by connecting nuts, for example.

In the present invention, the shape of the first and second annular bosses is not limited to a standard circle, and may be an oval shape, a deformed convex structure such as a special shape, or the like, which means that one or more structures are provided circumferentially around the outer wall of the adjusting screw 1032 and convex radially outward continuously or at intervals, so that steps can be formed and the functions of supporting/limiting can be performed.

The upper portion of the adjusting screw 1032 is configured to be rotatably engaged with the supporting block 1033, and the lower portion of the adjusting screw 1032 is configured to be rotatably and vertically threadedly engaged with the supporting plate 1031, so that the supporting block 1033 is not rotated when the adjusting screw 1032 is rotated in the circumferential direction, and the supporting block 1033 is moved in a vertically moving manner while the adjusting screw 1032 is moved in a vertically moving manner, together with the adjusting large plate 102.

In some embodiments, the above embodiments may be further modified such that a rotatable, liftable screw engagement is configured between an upper portion of the adjusting screw 1032 and the support block 1033, and a lower portion of the adjusting screw 1032 is configured to rotatably engage the support plate 1031. Wherein, set up the screw hole on the supporting shoe 1033, adjusting screw 1032 screws into the screw hole on the supporting shoe 1033, and adjusting screw 1032's lower part is equipped with the rotation cooperation portion, is equipped with the opening or the hole of cup jointing in the rotation cooperation portion outside on the backup pad 1031. In this way, when the adjusting screw 1032 is rotated, the supporting block 1033 can be driven to move up and down together with the adjusting plate 102 according to the screw engagement between the supporting block 1033 and the adjusting screw 1032.

In some embodiments, the support plate is fastened and connected with the hanging beam by adopting the locking structure, so that the installation mode is simplified, and the locked fixed connection is more reliable.

As illustrated in fig. 2, 4 to 10, a plurality of rail connection blocks 10311 are provided on the support plate, wherein the rail connection blocks 10311 are embedded into the sliding grooves in the hanging beam, so that the locking connection between the support plate 1031 and the frame body 101 can be quickly achieved by adjustment after the sliding grooves are embedded.

In some embodiments, part of the support plates may be provided at corners of the frame body 101, for example, four corners of the frame body 101 are provided with the support plates 1031, respectively, so that the support plates 1031 can provide good support for the frame body 101, so that the frame body 101 can provide good rigidity even in a small volume.

In some embodiments, the relevant components in the OHT suspension lift system may be installed by some structural components, as the accommodation space may be formed below the accommodation large plate 102.

As illustrated in fig. 2, the ceiling mounting assembly further includes a plurality of first hoisting assemblies 104, one ends of the first hoisting assemblies 104 are fixedly connected to the lower surface of the adjusting large plate 102, and the other ends of the first hoisting assemblies are used for being cooperatively connected with the OHT suspension type lifting system, wherein the height of the first hoisting assemblies is not less than the height of the wireless power collector of the OHT suspension type lifting system.

In some examples, the first lifting assembly 104 may be a pin alignment and self-locking device, such as the pin locking after alignment by four angular pin positions when the lifting platform assembly illustrated in fig. 1 is raised to a predetermined height. Referring to fig. 13 and 14, the pin 301 of the lifting platform assembly 3 is cooperatively connected with the first lifting assembly 104, and the height of the first lifting assembly 104 is not less than that of the wireless power takeoff 302, so that in the cooperative connection of the first lifting assembly 104 and the lifting platform assembly 3, the functions of alignment, locking and the like can be realized, corresponding installation space can be provided for the wireless power takeoff 302, the deployment of the wireless power takeoff 302 in an OHT suspension type lifting system is facilitated, the occupation of the space by the OHT suspension type lifting system is further facilitated to be saved, and the flexible deployment of the OHT suspension type lifting system in a factory workshop is facilitated.

As shown in fig. 2, the ceiling mounting assembly further includes a plurality of belt sensors 107, such as a first belt sensor 1071, a second belt sensor 1072, etc., which are provided on the lower surface of the adjustment plate 102, so that the relative height position of the elevating platform assembly 3 connected under the belt in the OHT suspension type elevating system can be obtained by the detection results of the belt sensors.

For example, the first belt sensor 1071 and the second belt sensor 1072 constitute a correlation detection device, and it is possible to perform approximate detection and determination as to whether the thickness of the belt wound around the winding drum of the flexible belt in the lifting/lowering unit 2 is in place, for example, when the flexible belt is gradually wound around the winding drum during lifting, the winding drum around which the synchronous belt is wound becomes thicker and the outer diameter thereof 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 to form a thickness of the belt roll, and the thickness is thickened until the belt roll is blocked between the first belt sensor 1071 and the second belt sensor 1072, and the two sensors are triggered to output a detection result. It is easy to understand that, when the lifting platform descends or the height does not reach the preset height, there is no shielding between the first belt sensor 1071 and the second belt sensor 1072, and no detection result is output.

In practice, the belt sensor may be fixedly connected to the adjustment plate 102 by an L-shaped structure, and the L-shaped structure (e.g., the first belt sensor 1071) may also be a structure with reinforcing ribs, thereby improving the structural rigidity of the assembly.

As shown schematically in fig. 2, the ceiling mounting assembly further comprises a plurality of second hoisting assemblies 108, wherein the second hoisting assemblies 108 are fixedly connected to the hoisting beams of the frame body 101, and the second hoisting assemblies 108 can then be used for suspending an electric cabinet of the OHT suspension type lifting system (see electric cabinet shown schematically in fig. 1).

In some embodiments, the lifting platform can take electricity wirelessly from the electric cabinet, so that a relevant fixing support can be arranged below the adjusting large plate, and the relevant structure for wireless electricity taking is supported by the fixing support in a space below the adjusting large plate.

As illustrated in fig. 2 and 12, after the electric cabinet is suspended by adopting the second hoisting assembly, a cable of the electric cabinet can be led out to a space below the adjusting large plate 102 to realize a wireless power taking scheme. Specifically, the ceiling mounting assembly further includes a wireless power supply assembly 106, wherein the wireless power supply assembly 106 is fixed and supported by a plurality of fixing brackets 1062, wherein the fixing brackets 1062 are disposed on the lower surface of the adjusting large plate 102, and the fixing brackets 1062 support a cable 1061 for providing wireless power to the electric cabinet, so that a wireless power taking device (not shown in the figure) in the OHT suspension type lifting system can take power from the cable 1061 wirelessly.

In some embodiments, by providing associated detection assemblies in the space below the adjustment large plate, the relevant operation (e.g., lifting) of the OHT suspension lift system can be detected and controlled in real time by the detection assemblies.

As illustrated in fig. 2, 15 to 16, the ceiling mounting assembly further comprises a plurality of detection assemblies 109, wherein the detection assemblies 109 are arranged in the space below the adjustment large plate 102 for detecting the OHT suspension lifting system. Specifically, two sets of detection assemblies 109 are employed to face the lift platform of the OHT overhead hoist system.

Preferably, the detection assembly 109 can include a first detection end 1091 and a second detection end 1092, wherein the first detection end 1091 is mounted on the lower surface of the adjustment plate 102, and the second detection end 1092 is mounted on the lift platform 3 of the OHT suspension lift system so as to follow the lift platform up or down, so that the lift main position detection is accomplished by the cooperation detection between the first detection end and the second detection end.

In one example, as illustrated in fig. 15 to 17, the first detection end 1091 of the detection assembly 109 employs three detectors, i.e., a first detector 10911, a second detector 10912, and a 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 is configured to detect with a photo detector in the form of a different position of a baffle, such as a first baffle and a second baffle, which are mounted on the lift platform of the OHT suspension lift system. Thus, the detector may preferably be a photodetector, whereby the baffle cooperates with the photodetector to perform the detection.

Preferably, as illustrated in fig. 16, the same baffle structure 10921 may be used to implement the first baffle and the second baffle functions by providing different height positions of the baffle structure 10921, respectively, so as to further reduce space occupation, wherein the mounting seat 10922 is used for connection with the lifting platform 3 (refer to fig. 13 to 14 for illustration).

In one example, the detector may be utilized in conjunction with the baffle detection results to effect a related maneuver, such as a wireless power take.

For example, when the lifting platform of the OHT suspended lifting system rises to the ceiling, the first baffle and the first detector 10911 complete the cooperation detection first, and find that the lifting platform is about to approach the ceiling in time, so that preparation for wireless power taking can be made; if the lifting platform continues to ascend, the first baffle plate and the second detector 10912 complete the cooperation detection, and timely find that the lifting platform enters a wireless power taking range and can perform wireless power supply operation; if the lifting platform continues to rise, the second baffle and the third detector 10913 complete the cooperation detection, and timely find that the lifting platform has risen to a limit state, and can stop rising, so as to provide continuous power supply for wireless power taking and realize stable and reliable wireless power supply.

For example, when the lifting platform moves down from the ceiling, the corresponding operation (such as disconnecting the wireless power supply) can be completed through the cooperation detection between the detector and the baffle, and the description is not expanded.

In some embodiments, good electromagnetic shielding can be achieved by adjusting the space below the large plate, electromagnetic interference possibly caused by a wireless power-taking cable is reduced, and reliability is improved.

As illustrated in fig. 2, the ceiling mounting assembly further includes a cable shielding conduit 105, wherein the cable shielding conduit 105 may be specifically laid out according to the space constraint under the large adjustment plate 102, and the cable shielding conduit 105 is disposed on the lower surface of the large adjustment plate 102 by a plurality of supporting members 1051, and the cable shielding conduit 105 may be a conduit capable of shielding electromagnetic signals, so as to quantitatively shield electromagnetic signals emitted from the cable 1061 between the electric cabinet and the wireless power collector.

In some embodiments, in the foregoing embodiments, the frame body 101 may be a unitary frame including four hanging beams, where the number of groups of the adjusting mechanisms 103 is eight, where four groups of the adjusting mechanisms 103 are disposed at corners of the frame body 101, and four groups of the adjusting mechanisms 103 are disposed in the middle of corresponding hanging beams, so that not only can good support be provided for the frame body 101, but also good support can be provided for the adjusting large plate 102.

Based on the same inventive concept, the present application also provides an OHT overhead hoist system. Referring to the foregoing illustration of fig. 1, the OHT suspension lift system is fixedly mounted below a ceiling by the ceiling mounting assembly according to any one of the present disclosure, so that not only can the space between the track and the ceiling be fully utilized, but also flexible deployment and application of the OHT suspension lift system in a workshop can be facilitated.
