Description

Technical Field

[0001] This utility model relates to the field of wafer manufacturing technology, and more specifically, to a drawer-type basket. Background Technology

[0002] Baskets are indispensable carriers in the wafer manufacturing process, playing a crucial role in wafer dicing and packaging / testing. Currently, the most common basket sizes on the market are 13-slot and 25-slot.

[0003] To meet the requirement of precise placement of the wafer rings, the inner cavity of the basket is symmetrically equipped with equally spaced slots. However, due to the small distance between adjacent slots on the same side, in actual operation, personnel need to visually inspect the slots on both sides of the basket to ensure that the wafer rings can be accurately placed into the corresponding slot positions. After placement, it is also necessary to check whether the wafer rings are placed at an angle to avoid collisions with the machine arm during operation, which could cause the machine arm to break or the machine arm to directly hit the wafer on the ring, resulting in wafer breakage.

[0004] In view of this, we propose a drawer-type basket. Utility Model Content

[0005] The purpose of this utility model is to provide a drawer-type basket to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drawer-type basket includes a frame and slots symmetrically installed on the inner wall of the frame. At least two slots are symmetrically opened on opposite sides of the two slots. Each slot has a sliding rail at the bottom of its inner cavity. A support frame is slidably connected between two sliding rails at the same horizontal height. A wafer iron ring is placed on the support frame and moves into the frame as the support frame slides.

[0008] As a further embodiment of this utility model: a mounting plate is snapped onto the top of the frame, and a handle is rotatably connected to the middle of the top of the mounting plate; a notch is opened at one corner of the mounting plate, and the side of the mounting plate where the notch is located is equal in length to the side of the frame adjacent to it; the notch space formed by the mounting plate, the frame and the groove block is a limiting point.

[0009] As a further embodiment of this utility model: the support frame includes a frame body and a handle, the edge shape of the entire side of the frame body where the handle is installed is the same as the edge shape of the side where the notch of the mounting plate is located; the positions of the handles of adjacent support frames are misaligned.

[0010] As a further embodiment of this utility model: the exposed end of the groove block is rotatably connected to a rotating rod, and the rotating rod rotates to a limit position to limit the bearing frame.

[0011] As a further embodiment of this utility model: a limiting block is fixed on the sliding track of the groove block, and the limiting block limits the sliding distance of the bearing frame within the sliding track.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When using this drawer-type basket, place the wafer iron ring on the support frame, then push the support frame to slide into the frame, thereby moving the wafer iron ring synchronously into the frame. This allows the wafer iron ring to be placed in the designated slot intuitively, simplifying the operation steps and improving the efficiency of the operation.

[0014] 2. When using this drawer-type basket, it can prevent the machine arm from breaking due to the iron ring being inserted obliquely into the slot, or the machine arm directly hitting the wafer on the iron ring, which could cause the wafer to break. This reduces machine wear and wafer scrap rate, thereby achieving the goal of saving costs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example

[0022] Currently, to meet the requirement of precise placement of wafer rings, most baskets have symmetrically spaced slots 105 inside. However, because the distance between adjacent slots 105 on the same side is too small, in actual operation, personnel need to visually inspect the slots 105 on both sides of the basket to ensure that the wafer rings can be accurately placed into the corresponding slots 105. After placement, it is also necessary to check whether the slots 105 are placed at an angle to avoid the wafer rings being placed at an angle, which could cause the machine arm to collide with the wafer during operation, resulting in the machine arm breaking or the machine arm directly hitting the wafer on the ring, causing the wafer to crack.

[0023] Therefore, please refer to Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a drawer-type basket, which includes a frame 100 and slots 102 symmetrically installed on the inner wall of the frame 100. At least two slots 105 are symmetrically provided on opposite sides of the two slots 102. If the distance between adjacent slots 105 on the same side is too small, it is very easy to cause an oblique insertion when inserting a wafer iron ring. Therefore, a sliding rail 106 is provided at the bottom of the inner cavity of each slot 105, and a support frame 1 is slidably connected between two sliding rails 106 at the same horizontal height. 10. In use, place the wafer iron ring on the support frame 110 and push the support frame 110 to move along the sliding track 106 to move the wafer iron ring into the frame 100. The wafer iron ring is placed directly into the designated slot 105, which simplifies the operation steps and improves the efficiency of the operation. At the same time, it can avoid the machine arm from breaking due to the iron ring being inserted obliquely into the slot 105, or the machine arm directly hitting the wafer on the iron ring and causing the wafer to break. This reduces machine wear and wafer scrap rate and achieves the purpose of saving costs.

[0024] To facilitate the movement and carrying of the drawer-type basket, a mounting plate is snapped onto the top of the frame 100. A handle 101 is rotatably connected to the center of the top of the mounting plate. By rotating the handle 101, it can be rotated to a position perpendicular to the mounting plate during use, making it easy to apply force to the drawer-type basket for movement and carrying. When not in use, the handle 101 can be rotated to a position horizontal to the mounting plate, thereby reducing the impact of the handle 101 on the use of the drawer-type basket and saving space.

[0025] To facilitate the limiting of the support frame 110, a notch is made at one corner of the mounting plate, and the side of the mounting plate with the notch is the same length as the adjacent side of the frame 100. The side of the frame 100 with the same length as the notch on the mounting plate is called the short side of the frame 100. This irregular design causes a section of the slot block 102 installed on the short side of the frame 100 to be exposed. At the same time, the notch space formed by the mounting plate, the frame 100 and the slot block 102 is the limiting point 104. The exposed end of the slot block 102 is rotatably connected to a rotating rod 103. When the support frame 110 is inserted into the frame 100, the rotating rod 103 is rotated to the limiting point 104, thereby limiting the support frame 110 by the rotating rod 103 to reduce the occurrence of the support frame 110 sliding out of the frame 100 when shaking.

[0026] The support frame 110 consists of a frame and an easy-to-operate handle 111. To optimize the limiting function of the rotating rod 103 on the support frame 110, the edge shape of the side on which the handle 111 is installed on the frame is designed to match the edge shape of the side where the notch of the mounting plate is located. This design ensures that the rotating rod 103 can accurately limit the support frame 110. At the same time, considering that the spacing between adjacent slots 105 is usually very tight in practical applications, in order to improve the ease of pulling out the support frame 110, a staggered design is adopted for the handles 111 of adjacent support frames 110. This ensures that the handles 111 of adjacent support frames 110 will not interfere with each other, and users can easily and quickly pull out the designated support frame 110, thereby significantly improving work efficiency.

[0027] Please see Figure 3 As shown, given that the sliding rail 106 may not be fully embedded in the slot 105, but is designed so that one side does not contact the slot 105, if the sliding rail 106 and the slot 105 are the same length, this design may cause the carrier frame 110 to slip out of the frame 100. For this reason, the sliding rail 106 on the slot block 102 is equipped with a limiting block 107, which is used to precisely control the sliding range of the carrier frame 110 on the sliding rail 106. Importantly, the installation position of the limiting block 107 is usually set according to the size of the carrier frame 110 to ensure that the carrier frame 110 can be completely pushed into the sliding rail 106, thereby effectively preventing it from slipping out.

[0028] In summary, the working principle of this solution is as follows:

[0029] When it is necessary to place the wafer iron ring, firstly, pull the carrier frame 110 out of the frame 100, place the wafer iron ring on the carrier frame 110, and then push the carrier frame 110 to slide along the sliding track 106 into the frame 100, thereby driving the wafer iron ring into the frame 100 until the carrier frame 110 touches the limiting block 107 and stops. Finally, rotate the rotating rod 103 to rotate to the limiting position 104, thereby limiting the carrier frame 110.

[0030] When it is necessary to remove the wafer iron ring, firstly, rotate the rotating rod 103 to the side away from the limit point 104, thereby releasing the limit on the carrier frame 110. Then, pull the carrier frame 110 with the handle 111 to push the wafer iron ring completely out of the frame 100. Finally, remove the wafer iron ring and push the carrier frame 110 to slide along the sliding track 106 into the frame 100 until the carrier frame 110 touches the limit block 107 and stops.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
