Description

Technical Field

[0001] This application relates to the field of factory equipment technology, and in particular to a crane track inspection device. Background Technology

[0002] Within a wafer fabrication plant (FAB), critical track components of the automated material handling system (AMHS) overhead cranes must be inspected regularly, including levelness, cable trays, and guide rails.

[0003] In routine inspections, maintenance, or troubleshooting, elevated work is often carried out using equipment such as lifts. This requires inspectors to work at heights using the equipment to inspect the overhead crane tracks and the structures and components on them. During the inspection, one person often needs to climb up to inspect while two others move and position the lifting equipment so that the inspectors can inspect the overhead crane tracks at different locations.

[0004] However, the inspection method of working at height requires the participation of multiple people, and the equipment needs to be moved and positioned during the inspection process, which is extremely inefficient, increases operating costs, and poses safety risks such as personnel falling or tools / parts falling and injuring people. Utility Model Content

Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one.

[0049] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] Currently, in wafer fabrication plants (FABs), it is necessary to regularly inspect overhead crane tracks, including checking their levelness, cable trays, and guide rails. Existing technologies often involve using lifting equipment for these tasks, requiring at least two people to move or hold the equipment, while one person must climb to inspect the overhead crane tracks.

[0052] Because the total length of the overhead crane track is quite long, taking the total length of the overhead crane track as 3,000 meters as an example, it takes about 7,125 hours to conduct a comprehensive inspection by working at height, with an operation efficiency of about 2m / 570s. The inspection efficiency is extremely low, which increases the operating cost. In addition, there are safety risks such as personnel falling, tools or parts falling and injuring people during the inspection process.

[0053] Please refer to Figures 1 to 4 The overhead crane track 600 inspection device provided in this embodiment includes: a mounting frame 100, a traveling mechanism 200, a steering mechanism 300, a detection mechanism 400, and a pushing component 500.

[0054] The mounting frame 100 has a mounting surface on its top surface. The traveling mechanism 200 includes traveling wheels 210 and buffer wheels 220. Multiple traveling wheels 210 are located on both sides of the mounting frame 100. The axles of the traveling wheels 210 are horizontally oriented to allow them to travel along the overhead crane track 600. The buffer wheels 220 are located on the mounting frame 100, and their axles are vertically oriented to allow them to abut against the inner wall of the overhead crane track 600. The steering mechanism 300 includes a steering wheel 310 located on the mounting frame 100. The axles of the steering wheels 310 extend vertically and allow them to travel along the steering guide rail of the overhead crane track 600. The detection mechanism 400 is located on the mounting frame 100 and is used to detect the overhead crane track 600. The pushing assembly 500 is located at the bottom of the mounting frame 100 and is used for manual pushing or pulling.

[0055] Specifically, in this embodiment, the detection mechanism 400 is mounted on the mounting frame 100 to detect the crane track 600 during the operation of the crane track 600 inspection device provided in this embodiment.

[0056] In use, the connecting rail is lowered until it is below the mounting frame 100, allowing the traveling wheels 210 to drive horizontally into the connecting rail. Then, the mounting frame 100 is placed into the overhead crane track 600 via the connecting rail, with the traveling wheels 210 on both sides of the mounting frame 100 positioned on the overhead crane tracks 600 on either side. The connecting rail is then moved upwards to the normal operating height, allowing the overhead crane track 600 inspection device provided in this embodiment to follow the connecting rail and connect into the overhead crane track 600.

[0057] The component 500 is pushed or pulled to move the mounting frame 100 along the extension direction of the overhead crane track 600 via the traveling wheels 210. During the movement, the buffer wheels 220 can abut against the inner wall of the overhead crane track 600 and rotate, so that there is a certain distance between the mounting frame 100 and the inner wall of the overhead crane track 600, avoiding collisions and scrapes between the mounting frame 100 and the detection mechanism 400 and the overhead crane track 600 due to deviation in the direction of movement.

[0058] When the crane travels to the turning point of the overhead crane track 600, the steering wheels 310 on both sides of the mounting frame 100 can enter the steering guide rail and travel along the steering guide rail, so that the crane track 600 inspection device can smoothly and seamlessly follow the turn.

[0059] In this embodiment, the inspection mechanism 400 can perform inspections along the overhead crane track 600, resulting in high inspection efficiency. Only one person is needed to push or pull the inspection device to inspect the overhead crane track 600, specifically increasing the work efficiency to 0.35 m / s, significantly improving operational efficiency. In this embodiment, the total length of the overhead crane track 600 is 3000 m. A comprehensive inspection of the overhead crane track 600 in this embodiment can be shortened to 48 hours, requiring minimal personnel and avoiding personnel working at heights, thus reducing operating costs and significantly lowering safety risks.

[0060] In this embodiment, there are four driving wheels 210, which are arranged in a rectangular shape along the circumference of the mounting frame 100 to support the mounting frame 100.

[0061] In this embodiment, the steering mechanism 300 further includes a horizontal drive assembly. The horizontal drive assembly is disposed on the mounting bracket 100 and is connected to the steering wheels 310 in a driving manner. There are at least two steering wheels 310, which are respectively located on both sides of the horizontal drive assembly. The horizontal drive assembly drives the plurality of steering wheels 310 to move in the horizontal direction to enter or exit the steering guide rail.

[0062] Specifically, in this embodiment, the horizontal drive assembly is disposed on the mounting surface of the mounting bracket 100. The moving end of the horizontal drive assembly is relatively long and extends in the same direction as the two drive wheels. Multiple steering wheels 310 are respectively disposed at both ends of the moving end.

[0063] In this structure, the horizontal drive component can be controlled to drive the moving end to move to both sides of the mounting frame 100, thereby adjusting the position of the two steering wheels 310. Since the steering track is usually set on the inner wall of one side of the turning point of the overhead crane track 600, when the overhead crane track 600 inspection device travels to the turning point, the horizontal drive component is controlled to drive the moving end to move, so that the steering wheel 310 on the side close to the turning track extends out of the mounting frame 100, so that when traveling to the turning point, the steering wheel 310 can enter the turning track, thereby realizing the turning of the overhead crane track 600 inspection device.

[0064] In this embodiment, the horizontal drive assembly includes a drive shaft 320 and a transmission assembly. The drive shaft 320 is vertically mounted on the mounting frame 100, with one end of the drive shaft 320 located below the mounting frame 100 and the other end serving as the drive end and located above the mounting frame 100. The transmission assembly includes a gear 330 and a rack 340. The gear 330 is located at the drive end, and the rack 340 extends horizontally. Multiple steering wheels 310 are respectively located at both ends of the rack 340.

[0065] Specifically, in this embodiment, the moving end is the rack 340, and there are two guide wheels respectively disposed at both ends of the rack 340. The rack 340 and the drive shaft 320 are driven by a gear 330 at the drive end. When adjusting the position of the two guide wheels, the drive shaft 320 can be held and rotated. The rack 340 moves horizontally under the action of the gear 330, thereby driving the two guide wheels to move horizontally.

[0066] In this embodiment, the pushing component 500 includes a pusher 510 and a limiting member 520. The pusher 510 is located below the mounting bracket 100 and is rotatably connected to the mounting bracket 100. The limiting member 520 is located on one side of the pusher 510 and is used to limit the rotation angle of the pusher 510.

[0067] In this embodiment, the pusher 510 is hinged to the mounting bracket 100 for rotational connection. A limiting member 520 is mounted on the mounting bracket and located on one side of the pusher 510. When the pusher 510 rotates to 60°, its top end abuts against the limiting member 520, preventing further rotation. At this point, the pusher 510 can be pushed further to move the inspection device on the overhead crane track 600.

[0068] Furthermore, in this embodiment, the push member 510 has a tubular structure and an internal space. The drive shaft 320 is located within the space. The horizontal drive assembly also includes a universal joint 350, a handle 360, and a fixing member 370. The universal joint 350 is located on the drive shaft 320, the handle 360 ​​is connected to the universal joint 350, and the fixing member 370 is located on the outside of the handle 360, with the outer wall of the fixing member 370 abutting against the inner wall of the push member 510. The handle 360 ​​can rotate within the fixing member 370, and both the fixing member 370 and the handle 360 ​​rotate with the push member 510.

[0069] Specifically, in this embodiment, one end of the universal joint 350 is connected to the drive shaft 320, and the other end is connected to the top of the handle 360. The fixing member 370 is sleeved on the handle 360. The inner wall of the fixing member 370 is in contact with the handle 360 ​​but not connected, so that the handle 360 ​​can rotate within the fixing member 370, thereby driving the drive shaft 320 to rotate, and thus realizing the drive of the gear 330 and the rack 340.

[0070] The bottom end of the drive shaft 320, the universal joint 350, the handle 360, and the fixing part 370 are all set in the space inside the push part 510, which greatly reduces the required installation space. With the connection of the universal joint 350, the handle 360 ​​can rotate with the push part 510. After rotation, the handle 360 ​​can still be rotated to drive the drive shaft 320 to rotate. It is very convenient to use and has a small structure, making it very suitable for use in factory workshops.

[0071] Furthermore, in this embodiment, the bottom end of the grip 360 is provided with an external part 361. The external part 361 covers the bottom end of the push member 510 and can rotate relative to the push member 510. With this structure, the grip 360, universal joint 350 and drive shaft 320 can be rotated by rotating the external part 361. Since the external part 361 is located outside the setting space, it is more convenient for the user to rotate and use.

[0072] In this embodiment, mounting bracket 100 has mounting slots at both ends. The traveling mechanism 200 also includes a buffer member 230, which is disposed within the mounting slot and extends out of the mounting slot at one end. There are at least two mounting slots and buffer members 230, which are respectively and correspondingly disposed on both sides of the mounting bracket 100. There are multiple buffer wheels 220, which are respectively disposed at the ends of multiple buffer members 230 away from the mounting slots.

[0073] In this embodiment, the mounting slots are provided on both ends of the mounting frame 100, and the openings of the mounting slots face away from the mounting frame 100. The buffer member 230 is provided in the mounting slot, and the buffer wheel 220 is provided on the buffer member 230. The maximum distance between the two buffer wheels 220 on both sides of the mounting frame 100 is greater than the width of the mounting frame 100, and also greater than the maximum distance between the drive wheels on both sides of the mounting frame 100.

[0074] Under this structure, when the travel direction of the inspection device on the overhead crane track 600 deviates from the preset route, the buffer wheels 220 on both sides of the mounting frame 100 can first abut against the inner wall of the overhead crane track 600, so as to avoid friction and collision between the mounting frame 100, the drive wheel or the detection mechanism 400 and the side wall of the overhead crane track 600, which would cause damage to the overhead crane track 600 or the detection components.

[0075] In this embodiment, the traveling mechanism 200 further includes a damping spring 240, which is disposed in a mounting groove. One end of the damping spring 240 is located at the bottom of the mounting groove, and the other end abuts against the buffer member 230. A limiting groove is provided on the side wall of the mounting groove, and the extending direction of the limiting groove is the same as the extension direction of the damping spring 240. A slider adapted to the limiting groove is provided on one side of the buffer member 230, allowing the buffer member 230 to slide along the limiting groove.

[0076] Specifically, the end of the buffer 230 is set in the mounting groove and connected to the damping spring 240 at the bottom of the mounting groove. When the buffer wheel 220 comes into contact with the side wall of the overhead crane track 600, the buffer wheel 220 moves into the mounting groove under pressure, thereby squeezing the damping spring 240 to relieve pressure and achieve a buffering effect, thus preventing the buffer wheel 220 from deforming or being damaged after multiple collisions.

[0077] In this embodiment, there are four buffer wheels 220, and two mounting wheels are provided on each side of the mounting frame 100. The two mounting wheels on the same side are spaced apart and their orientation is the same as the extension direction of the overhead crane track 600. Under this structure, the two mounting wheels on the same side will contact the side wall of the overhead crane track 600 when traveling, thereby ensuring that the moving direction of the mounting frame 100 is the same as the extension direction of the overhead crane track 600.

[0078] In this embodiment, a first mounting portion 110 extending vertically is provided on the mounting surface. The detection mechanism 400 includes a plurality of first detection elements 410, which are spaced vertically on the first mounting portion 110 and form a first detection group. There are two first detection groups, located on both sides of the mounting frame 100, and the detection ends of the first detection elements 410 face both sides for detecting the state of the wire groove 610.

[0079] Specifically, in this embodiment, the first detection element 410 is an optical fiber sensor and there are a total of 8 groups, each group of optical fiber sensors includes a transmitter and a receiver.

[0080] Taking a first detection group as an example, the first detection group is located at one end of the mounting frame 100. The first mounting part 110 includes a vertically extending setting part 111 and a horizontally extending extension part. There are three extension parts, which are vertically spaced on the setting part 111. The distance between two adjacent extension parts is adapted to the thickness of the overhead crane track 600, so that the extension part at the top can be located above the upper overhead crane track 600, the extension part in the middle can be located between two overhead crane tracks 600, and the extension part at the bottom can be located below the bottom overhead crane track 600.

[0081] Furthermore, the protrusion extends horizontally toward the side away from the mounting bracket 100. Two receiving ends are provided below the top protrusion and two receiving ends are provided above the bottom protrusion. Correspondingly, two transmitting ends are provided above and below the middle protrusion, and each transmitting end is positioned opposite to the receiving end it faces.

[0082] In this structure, the transmitting end can send a signal and illuminate the corresponding overhead crane track 600. When the cable trough 610 of the overhead crane track 600 is broken, damaged, or the wires protrude, the signal received by the receiving end changes, indicating that the cable trough 610 of the overhead crane track 600 needs maintenance.

[0083] As an feasible approach, the positions of the transmitter and receiver can be interchanged, which can also achieve the inspection of the cable tray 610 of the overhead crane track 600.

[0084] It should be noted that the method of detecting the condition of the cable tray 610 using fiber optic sensors is a common technique in the prior art, and will not be described in detail here.

[0085] In this embodiment, the detection mechanism 400 includes a second detection element 420. The second detection element 420 is disposed on the mounting surface and faces the side of the mounting bracket 100. The second detection element 420 is used to photograph the steering guide rail. There are at least two second detection elements 420, each facing one side of the mounting bracket 100.

[0086] Specifically, in this embodiment, the second detection component 420 is a high-definition camera. The high-definition camera can take pictures of the steering guide rail and upload them to the control terminal, thereby observing whether there are cracks, damages or deformations in the steering guide rail, and thus realizing the inspection of the steering guide rail in the crane track 600.

[0087] In this embodiment, the detection mechanism 400 includes an electronic level 430. The electronic level 430 is disposed on the mounting surface and is used to detect the travel surface of the travel wheel 210.

[0088] In this embodiment, the electronic level 430 is mounted on the mounting surface at the top of the mounting bracket 100. Before use, the mounting surface can be leveled to zero the reading of the electronic level 430. During the operation of the crane track 600 inspection device, since the crane track 600 travels on the traveling wheels 210, the electronic level 430 can be used to check whether the crane track 600 traveled by the traveling wheels 210 is level. Please note that the above embodiments are for illustrative purposes only and do not imply limitation of this utility model.

[0089] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
