Technical Field
[0001] This utility model relates to the field of semiconductor manufacturing equipment technology, specifically a foldable and retractable material trolley for semiconductor production workshops. Background Technology
[0002] In semiconductor manufacturing, workshops need to frequently transfer and temporarily store materials of various specifications. Traditional material carts have the following problems: fixed storage space, making it difficult to adapt to materials of different sizes, resulting in low space utilization; lack of flexible classification structure, leading to damage or confusion due to mixed placement of materials; most carts cannot be folded or height adjusted, occupying a large amount of workshop space when idle, affecting production flow efficiency; and cumbersome manual adjustment operation, making it difficult to quickly adapt to the material storage needs of different production stages.
[0003] A search revealed existing technology (publication number: CN114735055B), which describes "an electronic trolley for wafer handling." This utility model includes a mobile platform with shock-absorbing wheels, a battery, and a controller. The mobile platform has a support platform with a positioning ring, a weighing sensor connected to the controller, and a reader. It is surrounded by a partitioned grille, and one side has a gantry structure push-pull handle with a display module (including a camera) and an arc-shaped handle. The display module and the push-pull handle are connected by C-type buckles and locking mechanisms. The wafer cassette is placed on the support platform and has an electronic tag. The shock-absorbing wheels have electronic braking components.
[0004] However, the device lacks folding and storage functionality, resulting in low space utilization. Furthermore, it lacks a flexible and adjustable storage area partition structure, limiting its adaptability. Utility Model Content

[0035] Specifically, a top cover 11 is provided on the top of the supporting base shell 1, and the top cover 11 is connected to the supporting base shell 1 by a snap fastener.
[0036] Specifically, four support plates 12 are welded to the bottom of the support base shell 1. The support plates 12 are located at the four corners of the support base shell 1, and two of them are provided with fixing pins for placing and fixing the top cover 11.
[0037] The supporting base 1 can hold items such as raw materials for production, and the bearing plate 36 can be used to hold wafers.
[0038] Furthermore, there are no restrictions on the items that can be placed in either of the two components mentioned above.
[0039] In this embodiment, the supporting base shell 1, the storage component 2, and the placement component 3 constitute a foldable and retractable semiconductor manufacturing workshop material trolley according to this application.
[0040] Example 2:
[0041] Specifically, the storage assembly 2 also includes: a control rod 22, which is slidably connected to the partition 21; and a locking block 23, which is slidably connected to the bottom of the partition 21 and cooperates with the positioning hole.
[0042] The locking block 23 is connected to the partition plate 21 by a spring.
[0043] In this embodiment, the control rod 22 drives the locking block 23 to slide, the locking block 23 is inserted into the positioning hole to fix the partition 21, and is unlocked by spring reset, thus fixing or adjusting the position of the partition 21.
[0044] Example 3:
[0045] In some embodiments, two-stage telescopic guide columns are provided at the other two corners inside the supporting base shell 1.
[0046] Specifically, the telescopic sleeve 32 is provided with three stages, with each stage slidingly connected to the previous stage and prevented from rotating by a protrusion limiting it.
[0047] Specifically, the placement component 3 also includes: a drive motor 31, which is connected to the bottom of the support base 1 by bolts and is located inside the telescopic sleeve 32; an adjusting screw 33, which is keyed to the output shaft of the drive motor 31 and threaded to the second-stage telescopic sleeve 32; and a threaded sleeve 34, which is slidably connected to the adjusting screw 33 by a protrusion, the protrusion preventing the threaded sleeve 34 from rotating relative to the adjusting screw 33, and threaded to the third-stage telescopic sleeve 32.
[0048] In addition, all drive motors 31 are electrically connected to the controller, which is located on the side wall of the supporting base 1.
[0049] It should also be noted that the fixed clamping block is connected to the bearing plate 36 by bolts, the slider clamping block is slidably connected to the bearing plate 36 by a sliding rail, and the sliding clamping block has a groove inside.
