Technical Field

[0001] This utility model relates to the field of monorail trolley technology, specifically a transport trolley that can be extended outwards. Background Technology

[0002] Automated air transport systems are an important type of automated transport system in semiconductor manufacturing plants, improving material transport efficiency. Among them, air transport vehicles are an important component of the air transport system.

[0003] The transport trolley can move freely on the lower flange of the I-beam rail. Currently, loading or unloading is generally done by transferring materials to the transport trolley using forks. However, due to space constraints, forks cannot be installed in various locations. Therefore, the transport trolley needs to have an outward-extending mechanical structure to achieve loading and unloading. To address this, a transport trolley that can extend outward has been developed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Please see Figures 1 to 3This utility model provides an embodiment of a transport trolley that can extend outwards, including a vehicle body 10 and an extension component 20 disposed on the vehicle body 10. The vehicle body 10 can be driven on a track 100. The extension component 20 includes a mounting frame 21 and a propulsion module 22 and a sliding structure 23 disposed on the mounting frame 21. The propulsion module 22 and the sliding structure 23 are parallel to each other, and a support frame 24 is slidably connected to the sliding structure 23. The sliding structure includes a slider and a slide rail that are fitted together. The support frame 24 and the mounting frame 21 are driven relative to each other through the slide rail and the slider. The support frame 24 is mainly used to carry products. The support frame 24 is linked to the propulsion module 22. That is, when the propulsion module 22 is driven, it can drive the support frame 24 to slide along the slide rail. The support frame 24 realizes the mechanical structure of extending outwards, realizes loading and unloading at specific positions, and avoids the problem of space limitation.

[0020] In this embodiment, the propulsion module 22 includes a drive motor and a lead screw transmission module, which enables the support frame 24 to expand outwards at a precise position.

[0021] The support frame 24 has a rotating shaft 25 at both ends, and a conveyor belt 26 is wrapped around the rotating shaft 25 at both ends. The mounting frame 21 has a drive motor 27 at the side end. The drive motor 27 is linked to any of the rotating shafts 25. When the drive motor 25 rotates, it can drive the conveyor belt 26 to roll. The conveyor belt 26 is used to support the product, and the rolling of the conveyor belt 26 can make the product located at the center position of the support frame 24, making the transmission process more stable.

[0022] Synchronous rollers 28 are provided at both ends of the rotating shaft 25. The synchronous rollers 28 on the same side are sleeved with synchronous belts 29, and the drive motor 27 is linked to any one of the synchronous rollers 28. In this embodiment, a support frame 24 is provided, and two conveyor belts 26 are covered on each support frame 24, which increases the bearing area. The synchronous rotation of the two conveyor belts 26 is achieved through the synchronous rollers 28 and the synchronous belts 29.

[0023] In other embodiments, multiple support frames 24 may be provided, each of which is connected to a propulsion module 21, enabling simultaneous multi-directional expansion.

[0024] The support frame 24 is also equipped with a travel limiter 30, which is located inside the support frame 24 and is located near the front and rear sides of the support frame 24. The conveyor belt 26 is also equipped with a limiting hole 31 for the movable shaft of the travel limiter 30 to extend out. After the product rolls and moves to the center position of the support frame 24 via the conveyor belt 26, the travel limiter 30 pops out its movable shaft and passes through the limiting hole 31, thereby positioning the conveyor belt 26 and preventing the conveyor belt 26 from sliding during the sliding of the vehicle body 10, which would cause the product to fall. The movable shaft of the travel limiter 30 can also act as a blocking effect, further improving the transportation stability of the transport trolley.

[0025] The vehicle body 10 is also equipped with a rotating module 11, and the expansion component 20 is installed on the rotating module 11. The rotating module 11 can drive the expansion component 20 to rotate freely 360 degrees, realize multi-directional expansion, and improve adaptability.

[0026] The vehicle body 10 includes a vehicle frame 12 and drive modules 13 arranged on both sides of the vehicle frame 12. The drive modules 13 are provided with movable wheels 14 inside, which are used to abut against the track 100. The movable wheels 14 on both sides of the drive modules 13 can clamp the track 100. At the same time, the movement of the vehicle body 10 is achieved by rotating the movable wheels 14.

[0027] The vehicle body 10 is also equipped with a track cleaning component 15, which includes a vacuum motor and a Y-shaped vacuum pipe connected to the vacuum motor. The Y-shaped vacuum pipe can generate negative pressure on both sides of the track 100 to absorb the debris falling from the track 100 and achieve a cleaning effect.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
