Technical Field

[0001] This utility model relates to the field of wafer loading and unloading machine technology, specifically to a wafer transfer box locking mechanism for a wafer loading and unloading machine. Background Technology

[0002] Wafer loading and unloading machines, also known as wafer loader machines, are key automated equipment in the semiconductor manufacturing process. They are installed in front of the front-end module of the equipment and serve as the window for wafer entry and exit. They are intelligent and flexible factory interface modules for tool automation. Their main function is to take wafers out of the wafer transfer box and accurately place them on the worktable of processing equipment such as lithography machines and etching machines, or to put the processed wafers back into the transfer box. During this process, the cleanliness of the wafers must be strictly maintained to ensure the quality of semiconductor production.

[0003] Existing wafer loading and unloading machines are widely used, but when transporting wafer transfer boxes, they are usually placed directly on the transport device without locking or limiting them. This can cause the wafer transfer boxes to shift during transport. Therefore, a wafer transfer box locking mechanism for a wafer loading and unloading machine is proposed to address the above problem. Utility Model Content

[0004] The purpose of this invention is to provide a wafer transfer box locking mechanism for a wafer loading and unloading machine, so as to solve the problem mentioned in the background art that the existing devices do not lock and limit the wafer transfer box.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wafer transfer box locking mechanism for a wafer loading and unloading machine includes a loading and unloading machine body. A platform is fixedly connected to the front side of the loading and unloading machine body. A fixed frame is fixedly connected to the front side of the loading and unloading machine body inside the platform. A symmetrically arranged sliding component is installed at the top of the fixed frame. A storage plate is installed at the top of the sliding component. A driving component is installed at the bottom of the storage plate. A vertical through hole is symmetrically opened inside the storage plate. A servo motor is inclined and fixedly connected to the bottom of the storage plate below the through hole. An inclined locking block is fixedly connected to the top of the output shaft of the servo motor.

[0007] Preferably, the shelf is positioned above the platform, and the output shaft of the servo motor and the locking block are both positioned inside the perforation.

[0008] Preferably, the sliding component includes a sliding frame fixedly connected to the top of the fixed frame, a sliding rail slidably connected to the inner side of the sliding frame, and the top of the sliding rail fixedly connected to the bottom of the shelf.

[0009] Preferably, the drive assembly includes a mounting plate installed at the bottom of the shelf, and a horizontally arranged bidirectional telescopic rod is fixedly connected to the bottom of the mounting plate.

[0010] Preferably, the mounting plate is bolted to the bottom of the shelf, and both output shafts of the bidirectional telescopic rod are horizontally aligned with the fixed frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting up a platform, a fixed frame, perforations, a servo motor, and a locking block, when the device needs to be used, the wafer transfer box can be placed on the platform and covered above the two perforations. Then, the servo motor is started, and the output shaft of the servo motor drives the locking block to rotate, so that the locking block rotates 90 degrees to lock the wafer transfer box. This design can lock the wafer transfer box and prevent the wafer transfer box from shifting during transportation.

[0013] 2. In this utility model, by setting up a sliding component, sliding frame, sliding rail, placement plate, driving component, mounting plate and bidirectional telescopic rod, after locking the wafer transfer box, the bidirectional telescopic rod is activated, so that the output shaft of the bidirectional telescopic rod at the end away from the loading and unloading machine body extends out and contacts the inside of the fixed frame, so that the placement plate slides above the fixed frame until the wafer transfer box moves to the bottom of the loading and unloading machine body, and the wafer can be loaded and unloaded. This design makes the structure of the device simpler and the transportation efficiency of the wafer transfer box higher. Attached Figure Description

[0025] Please see Figure 1-7 This utility model provides a technical solution:

[0026] A wafer transfer box locking mechanism for a wafer loading and unloading machine includes a loading and unloading machine body 1. A platform 2 is fixedly connected to the front side of the loading and unloading machine body 1. A fixing frame 3 is fixedly connected to the front side of the loading and unloading machine body 1 inside the platform 2. A sliding component 4 is symmetrically arranged at the top of the fixing frame 3. A storage plate 5 is installed at the top of the sliding component 4. A driving component 6 is installed at the bottom of the storage plate 5. A through hole 7 is symmetrically opened inside the storage plate 5, and a servo motor 8 is inclined and fixedly connected to the bottom of the storage plate 5 below the through hole 7. An inclined component 8 is fixedly connected to the top of the output shaft of the servo motor 8. The locking block 9 and the shelf 5 are set above the shelf 2. The output shaft of the servo motor 8 and the locking block 9 are both set inside the through hole 7. With the shelf 2, the fixing frame 3, the through hole 7, the servo motor 8 and the locking block 9 set, when the device needs to be used, the wafer transfer box can be placed on the shelf 5 and the wafer transfer box can be covered above the two through holes 7. Then the servo motor 8 is started, and the output shaft of the servo motor 8 drives the locking block 9 to rotate, so that the locking block 9 rotates 90 degrees to lock the wafer transfer box. This design can lock the wafer transfer box and prevent the wafer transfer box from shifting during transportation.

[0027] The sliding assembly 4 includes a sliding frame 41 fixedly connected to the top of the fixed frame 3. A slide rail 42 is slidably connected to the inner side of the sliding frame 41. The top of the slide rail 42 is fixedly connected to the bottom of the placement plate 5. The driving assembly 6 includes a mounting plate 61 installed at the bottom of the placement plate 5. A horizontally arranged bidirectional telescopic rod 62 is fixedly connected to the bottom of the mounting plate 61. The mounting plate 61 is installed at the bottom of the placement plate 5 by bolts. The two output shafts of the bidirectional telescopic rod 62 are horizontally aligned with the fixed frame 3. Through the sliding assembly 4, sliding frame 41, slide rail 42, placement plate 5, driving assembly 6, mounting plate 61, and bidirectional telescopic rod 62, after the wafer transfer box is locked, the bidirectional telescopic rod 62 is activated, causing the output shaft of the bidirectional telescopic rod 62 to extend away from the loading and unloading machine body 1 and contact the inner side of the fixed frame 3. This allows the placement plate 5 to slide above the fixed frame 3 until the wafer transfer box moves below the loading and unloading machine body 1, at which point the wafer can be loaded and unloaded. This design simplifies the structure of the device and increases the transportation efficiency of the wafer transfer box.

[0028] Workflow: Before use, power on the device and connect it to the controller. When the device is needed, place the wafer transfer box on the shelf 5 above the platform 2, covering the two perforations 7. Then, start the servo motor 8. The output shaft of the servo motor 8 drives the locking block 9 inside the perforation 7 to rotate, locking the wafer transfer box by rotating 90 degrees. Next, start the bidirectional telescopic rod 62 at the bottom of the mounting plate 61. The output shaft of the bidirectional telescopic rod 62 extends away from the loading / unloading machine body 1 and contacts the inside of the fixed frame 3. At this time, the slide rail 42 moves inside the slide frame 41, causing the shelf 5 to slide above the fixed frame 3 until the wafer is transferred. Once the wafer transfer box is moved below the main body 1 of the loading and unloading machine, the wafer can be loaded and unloaded. After loading and unloading, the bidirectional telescopic rod 62 is activated. The output shaft of the bidirectional telescopic rod 62 extends from one end of the main body 1 of the loading and unloading machine and contacts the inside of the fixed frame 3. At this time, the slide rail 42 moves inside the slide frame 41, and the wafer transfer box gradually moves away from the main body 1 of the loading and unloading machine. Finally, the servo motor 8 is activated, causing the locking block 9 to rotate 90 degrees and disengage from the wafer transfer box. This completes the use of the device. The design of the sliding component 4 and the drive component 6 makes the structure of the device simpler and the transportation efficiency of the wafer transfer box higher. The design of the locking block 9 and its connecting components can lock the wafer transfer box and prevent the wafer transfer box from shifting during transportation.
