Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of semiconductors, in particular to an overhead crane maintenance system. Background Art
[0002] With the continuous development of the semiconductor industry, manufacturers are faced with the challenge of improving production efficiency and reducing costs. Overhead Hoist Transport (OHT) is an important automatic handling system in semiconductor manufacturing plants, mainly used to transport wafer transfer boxes. By improving material transportation efficiency, reducing labor costs and reducing contamination risks, it has greatly improved the overall production process and achieved efficient process and inventory management. The overhead hoist transport system is currently not only used for direct transportation of wafer transfer boxes from tool to tool, tool to buffer and buffer to tool, but also for cross-zone or factory-wide transportation. The overhead hoist transport system (OHT) plays an important role in the semiconductor manufacturing process, bringing significant benefits to enterprises by improving production efficiency, reducing manual intervention, reducing contamination risks and saving space.
[0003] During use, the overhead crane needs regular maintenance or must be repaired due to a malfunction. Usually, the overhead crane is placed on a workbench (or fixture) that simulates the track on the ceiling of the factory for repair, maintenance or calibration. For example, when the running wheels of the overhead crane need to be calibrated and balanced, the overhead crane will be placed on the simulated track of the workbench (or fixture) for pushing and pulling. However, because there is no blockage at both ends of the simulated track, if too much force is applied during repeated pushing and pulling, the overhead crane will fall off the workbench (or fixture), causing irreversible damage to the overhead crane, which will not only cause economic losses and personal safety hazards, but also affect the online handling efficiency if a crane is damaged. At present, the temporary solution is to use 3M tape to paste, that is, to paste 3M tape on both ends of the simulated track, and to paste several layers of 3M tape to reach a certain thickness to block the movement of the overhead crane, but 3M tape is easy to wear and needs to be replaced frequently. More importantly, 3M tape cannot completely guarantee that the overhead crane is blocked. Therefore, the safety of the workbench (or fixture) responsible for repair, maintenance or calibration needs to be improved urgently. Utility Model Content

[0025] In this document, unless otherwise specified, the terms "upper", "lower", "left", "right", "inside", "outside", "front", "back", "top", "bottom", etc. are used to indicate directions or positional relationships based on the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction and operation. Therefore, they cannot be understood as limiting the present invention.
[0026] The following will describe the specific implementation of the utility model in more detail with reference to the schematic diagram. The advantages and features of the utility model will become clearer according to the following description. It should be noted that the drawings are all in a very simplified form and are not in exact proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.
[0027] The preferred embodiments of the present utility model are given below in conjunction with the accompanying drawings and described in detail.
[0028] Figure 1is a schematic diagram of an overhead travelling crane maintenance system according to an embodiment of the utility model. Figure 2 This is a schematic diagram of the coordination of the track and the block of the overhead crane maintenance system according to one embodiment of the utility model. Figure 1 and Figure 2 The embodiment of the utility model provides an overhead crane maintenance system, comprising a track 1, a vehicle body and a stopper 2; the vehicle body is movably arranged on the track 1 along the extension direction of the track 1;
[0029] The stopper 2 is arranged on the track 1, and is used to abut against the vehicle body to prevent the vehicle body from moving. Preferably, the stopper 2 has an inclined surface 21, and the inclined surface 21 is connected to the track 1. It can be understood that the lowest point of the inclined surface 21 is located on the upper surface of the track 1, and the inclined surface 21 smoothly transitions with the track 1, and the inclined surface 21 faces the vehicle body to prevent the movement of the vehicle body.
[0030] Normally, the vehicle body has a running wheel 3, and the running wheel 3 can roll on the track 1. It can be understood that the inclined surface 21 is parallel to the axis of the running wheel 3, and the inclined surface 21 is at an angle to the extension direction of the track 1, and further at an oblique angle. The running wheel 3 can roll on the inclined surface 21. The side of the block 2 that blocks the vehicle body is designed as an inclined surface, which plays a role in unloading the vehicle body. Compared with the vertical surface, it prevents direct impact and protects the running wheel 3. Furthermore, in the axial direction of the running wheel 3, the width of the inclined surface 21 is greater than the width of the running wheel 3, which can reduce the impact on the running wheel 3. Generally speaking, the angle between the inclined surface 21 and the extension direction of the track 1 is in the range of 30° to 50°. This angle range is a better solution, that is, it can effectively block the movement of the vehicle body and reduce the impact on the running wheel 3.
[0031] Since the movement of the vehicle body on the track 1 is reciprocating, generally speaking, blocks 2 are provided at both ends of the track 1. In this embodiment, there are two blocks 2, which are arranged at intervals on the track 1. It can be understood that the inclined surfaces 21 of the two blocks 2 are opposite, and the two blocks 2 are respectively located at the two ends of the track 1.
[0032] Generally speaking, the body of an overhead crane has at least two running wheels 3. In this embodiment, the body has an even number of running wheels 3, and the running wheels 3 are divided into two rows. The overhead crane maintenance system has two parallel tracks 1. Each row of running wheels 3 corresponds to one track 1, and each track 1 is provided with a block 2.
[0033] As configured above, the track 1 of the utility model simulates the track on the ceiling of the factory building, and the body of the overhead crane can move on the track 1, so as to simulate the normal working state of the overhead crane. In the process of maintaining, repairing or calibrating the overhead crane, it is necessary to repeatedly push and pull the body of the overhead crane on the track 1. A stopper 2 is set on the track 1, and the stopper 2 can block the movement of the body to prevent the overhead crane from falling from the track 1 due to excessive pushing and pulling force. Compared with the temporary measure of sticking 3M tape in the prior art, the stopper 2 is safe and effective in blocking the overhead crane, and the trouble of constantly replacing the 3M tape is also saved. The utility model provides an overhead crane maintenance system, which can simulate the normal working state of the overhead crane, and the setting of the stopper 2 makes the utility model also have higher safety, which can prevent the overhead crane from falling from the track 1, avoiding the economic losses and personal safety hazards caused by the falling of the overhead crane.
[0034] In this embodiment, the stopper 2 is connected to the track 1 through the fixing bracket 11. Specifically, a threaded hole is provided in the stopper 2, and a threaded hole is also provided in the fixing bracket 11. The stopper 2 is connected to the fixing bracket 11 through a bolt 4. Since the fixing bracket 11 is originally provided on the track 1 of the overhead crane maintenance system, no additional modification is required, which simplifies the modification difficulty of the utility model and is easy to install.
[0035] In this embodiment, the stopper 2 is made of metal, for example, the stopper 2 can be made of aluminum. Furthermore, the stopper 2 is a solid metal block, so it has a certain weight and can effectively block the movement of the vehicle body. The stopper 2 can also be made of other materials, which is not limited here.
[0036] The utility model does not limit the specific shape of the stopper 2, and only requires that the stopper 2 is provided with an inclined surface for blocking the vehicle body, and the stopper 2 can be a triangle or a trapezoid.
[0037] In summary, the utility model provides an overhead crane maintenance system, comprising a track 1, a car body and a stopper 2; the car body is movably arranged on the track 1 along the extension direction of the track 1; the stopper 2 is arranged on the track 1, and is used to abut against the car body to prevent the car body from moving. The utility model can simulate the normal working state of the overhead crane, and the setting of the stopper 2 makes the utility model also have higher safety, which can prevent the overhead crane from falling from the track 1, avoiding the economic losses and personal safety hazards caused by the falling of the overhead crane.
