[0014] In order to make the patent purposes, technical schemes and advantages of the utility model more clear and obvious, the utility model is further explained in detail below in combination with the drawings and examples.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0015] In order to explain the technical scheme of the utility model, the following is explained through specific examples.

[0016] In order to facilitate the description, only the parts related to the utility model embodiments are shown.

[0017] In combination Figures 1-3 As shown in the figure, the silicon wafer plate placing frame includes the rack 1, and a pair of cross bars 2 is arranged above the rack 1, and a plurality of load bars 3 is arranged below the rack 1, a plurality of limiting components 4 is arranged on the cross bar 2 along the length direction downward, and two limiting components 4 in adjacent intervals constitute a limiting interval, the limiting component 4 includes the limiting screw rod 41 installed on the cross bar 2, the bottom of the limiting screw rod 41 is the nut 42, the rotating drum 43 is sleeved on the limiting screw rod 41 on the nut 42, and the rubber sleeve 44 matched with the rotating drum 43 is arranged on the rotating drum 43.

[0018] The structure of the silicon wafer plate is compact and stable, which makes it have good physical and chemical stability. In this way, the silicon wafer plate also has wide application in the field of construction. In order to meet the needs of large-scale production and storage, the silicon wafer plate placing rack emerges as the times require.

[0019] After the silicon wafers are produced, a certain number of silicon wafers can be placed in the placement rack for drying. The placement rack includes a frame, and several limiting components are provided above the frame. Adjacent limiting components form a limiting interval, and a silicon wafer is placed on the carrier rod within one of the corresponding limiting intervals.

[0020] When placing silicon wafers into the rack, first move one wafer towards the frame. Once the bottom of the frame supports the wafer and it is placed vertically, fine-tune its position until it aligns with the limiting zone. Then push the wafer into the corresponding front and rear limiting zones, where the support rod supports it. Next, place the next wafer until the rack is full. During wafer placement, the side of the wafer contacts the rubber sleeve of the limiting component. The limiting component rotates to prevent hard contact with the wafer and scratching its surface.

[0021] Once the silicon wafers are stacked in the rack, the limiting component serves two purposes: firstly, it limits the movement of the wafers, preventing them from swaying left and right; secondly, it acts as a barrier, preventing adjacent wafers from contacting each other.

[0022] The installation structure of the limiting component is also relatively simple, which facilitates subsequent replacement, cleaning, and other related work. Figure 2 A pair of nuts, one upper and one lower, are located above the limiting screw. The upper nut is marked as 91, and the lower nut is marked as 92. The limiting screw is installed and fixed to the crossbar using the two nuts.

[0023] Specifically: First, the rotating drum is fitted onto the limiting screw, with the nut of the limiting screw supporting the rotating drum. Then, a rubber sleeve is fitted onto the rotating drum, followed by screwing a lower nut onto the limiting screw. Next, the limiting screw is inserted from the bottom of the crossbar upwards, and after it exits from the top of the crossbar, an upper nut is screwed in to lock it in place. At this point, the entire limiting assembly is installed.

[0024] As a preferred structure, such as Figure 1 There are three carrier rods 3, and each carrier rod 3 is equipped with a limit wheel 5 for rotation in the corresponding limit range.

[0025] During the stacking process, the carrier rod serves to support the silicon wafers. When stacking the silicon wafers, the upper part of the wafers is within the limiting range, and the lower part is within the limiting wheels. Therefore, the upper part of the silicon wafers is limited by two adjacent limiting components, and the lower part is limited by the limiting wheels.

[0026] As the silicon wafer is pushed into the front and rear limiting zones, it drives the rotating drums on both sides to rotate, and the limiting wheel at the bottom also rotates, making the entire stacking process more time-saving and labor-saving. During this process, the rubber sleeve protects the rotating drums. Because the limiting wheel is a rubber wheel with a certain degree of surface deformation, there is a certain frictional force between the limiting wheel and the silicon wafer when the limiting wheel carries it, preventing the silicon wafer from accidentally slipping out.

[0027] In this structure, such as Figure 3 The frame 1 is provided with material blocking components on both the front and rear sides. The material blocking components include a pair of material blocking frames 6 installed on the frame 1. A material picking groove 8 is formed above the material blocking frame 6. The groove is similar to a q-shaped groove with a notch. Material blocking rods 7 are placed inside the two material blocking frames 6. The material picking groove is slightly higher than the limiting range.

[0028] In this embodiment, silicon wafers can be stacked or retrieved from either the front or rear side of the rack. After stacking, two guide bars are placed at the bottom of the guide frame to further limit the silicon wafers from sliding out of the rack. To retrieve wafers from the front of the rack, first move the guide bar at the front upwards until it enters the retrieval slot, then move it outwards and lower it. At this point, the guide bar is higher than the silicon wafer, creating an opening at the front of the rack, allowing the silicon wafer to be pulled directly out from the front of the rack.

[0029] In the above structure, retaining rings 11 are formed at both ends of the material stop bar 7. The diameter is larger than the width of the material stop frame. The retaining rings can prevent the material stop bar from detaching from the material stop frame.

[0030] In addition, such as Figure 1 Each of the four corners of the top of the rack 1 is provided with a support bowl 10. In order to further improve the space utilization, several racks can be stacked one on top of the other as needed, and the four legs of the upper rack can be placed in the corresponding support bowls on the top of the lower rack to prevent the upper rack from shifting and improve stability.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
